I thought I would post this as the pc used in this review is very close to the top of the line imac. I included the pc specs below used in the review. Assuming the card in the imac is not the mobile version and the one listed in this review, those who wait are in for an amazing machine.

Has it frozen more than once since the time you've received it. Hopefully we can get some idea of what's going on. specify what CPU your system is running (2.93 or 3.06 ghz), along with info when you ordered the system, and when it was shipped.

so I have decided to get a new iMac 24inch 3.06. The question at hand is do I need to upgrade to the ATI Radeon HD 4850?
I dont play video games. I do edit large raw photo files with CS4 and I do use Final Cut Express for my video editing. What do you think. Thanks again in advance for your input.

If 10.5.7 does not fix the belief that wifi is causing freezes (or whatever it might be), we will be further down Apple's care list.

I bought an older 17" white iMac G5 for my work shop (not taking my newer aluminum one out there!) and it is a 1.8 ghz 80gb white 1st or second gen (I have not determined if it has the ambient sensor or not as of yet). I have read conflicting specs on whether or not this unit takes airport or airport extreme cards. Does anyone know for SURE? It will be a few days until I have this in my hands to look and I'd like to pre-order the card to expedite getting it set up.
I SHOULD be looking to an Apple A1126 Airport card if I am reading right.

I wrote it in another thread, but maybe I went OT, so...Does anyone know for sure if the ATI 4850 is the desktop version or the laptop version? I'm going to order the iMac24 but I want to be sure that the ATI card worth the money.

this is my first posting but I am desperate and need some help Apple could not provide. Here is my situation:
- new iMac 9,1 2,93 GHz, 4 GByte, ATI Radeon 4850
- pre-installed OS: Leopard 10.5.6
I have access to a MBP and an older iMac. The MBP had a defective logic board some months ago so I decided to copy its content (after repair) to an external hard drive. I used this hard drive as my primary OS and used it with the MBP or iMac and did have the same data all the time - excellent time-saver for me. Now the new iMac was shipped yesterday. I tried to boot it from the very same external hard drive as well. It worked but there are some annoying facts I need some help to deal with: I cannot activate sleep mode with the new iMac. The graphics card seems not to work well: stuttering screen saver, slow high definition video playback, slow spaces etc. I cannot dim the monitor's backlight with F1/F2 keys nor the monitor setup. All these problems disappear when I boot from the internal HDD but that is not an option for me. It looks like the "old" Leopard installations lacks of some drivers. Is there a way to add them, is there another solution or will an update of Leopard 10.5.7 - at least most likely - solve the problem? Apple support did not feel the need to help for "exotic configurations". I was told a fresh installation of a retail Leopard copy on an external hard drive COULD work (no guarantee) but it would take me too much time to re-configure and I don't feel the desire to set up my system fresh and new like in old Windows days.

Is there much difference from a stock iMac with Nvidia GT 130 vs ATI HD 4850 for gaming? It would be nice to be able just to buy a stock machines rather than a custom with the ATI for $50.
My real concern is overall gaming proformance and heat produced by the two cards. Current iMac has the ATI 2600 HD Pro, which I think is pretty slow compared.

correct me if I'm wrong but the 4850 has 800 pipelines and a 256 mb bus width as apposed to the 400 pipelines and 128 mb bus width in the 5750?
step backwards in terms of graphics?

I have an 2009 27inch imac with an ATI Radeon HD 4850 and was wondering if it is somehow possible to take the 5750 from a 2010 model and replace the 4850 with it?

I'm going to be ordering my new iMac within the next couple days but need a little advice first.
Obviously, the 4850 is more powerful, but if these two cards had the exact same specs, would ATI or nVidia be the better choice?
Which company is Apple leaning towards, which company produces better Mac drivers, how will OpenCL play into this, etc.

Those of you with the ATi 4850 card, is there any who have completed a reinstall and then still suffered with the freezing problem afterwards.
If so I am going to get back on to Applecare and demand a replacement.

It's avihappy again and I have another survey for you all. As you can see, there is now an iMac 4850 EFI firmware update available via software update. So can you: Find a test that will cause the iMac to freeze up. Do the update. (make sure you actually run the firmware updater tool, it may not run automatically when you install the update from Software Update.) Switch to WiFi. Do the test again. See if the iMac freezes!

I got my wife the new iMac with a Radeon 4850 to replace her ancient PC (and I meant ANCIENT) and she had massive issues with lockups due to overheating, especially when playing fullscreen 3D games like World of Warcraft in Mac OSX or any of her Windows XP games in bootcamp.
After the EFI Firmware Update 1.4 she's had far less issues, but she's still had 1 lockup (playing Diablo 2 stangly enough, a very old low detail game) and graphical glitches in WoW which caused her to stop playing out of fear of a lockup before it could happen.
Her computer temps are still extremely high but our house temp is only 72degrees.

Loving the new iMac revisions and have placed my order for the Core i7 configuration with 8 Gigs of RAM, the only thing that slightly concerns me is Apple putting the ATI 4850 GPU in this machine as this card has been around for well over a year. Having a young family my iMac really has to last me (current Mac is my old but faithful 800Mhz G4 Angle Poise 17" screen iMac) so don't want to get caught out with an "old" GPU that within a 2-3 years won't be able to cope with current day demands placed on it. My usage is photo manipulation, a bit of FCP and I want to be able to play some 3D games etc. but I'm by no means some games enthusiast who requires the highest frame rate, highest settings. Figure I have two option:
A. Bite the bullet now - this iMac has almost everything I want - been waiting for Quad Core desktop chip and LED screen but icing on the cake would have been better GPU and Blu-ray option.
B. Wait yet another update (figure March / April 2010) in the hope that Apple put in a more current GPU and possibly Blu-ray option. HOWEVER I figure that this is probably a fools game as who knows regarding Blu-ray and obviously a more current GPU will be fitted but probably won't be the most extreme one as Apple tend not to figure that this is a priority on the iMac.
My inclination is that this update will probably be absolutely fantastic and my GPU worries are probably unfounded as I'll never want to push it to gaming extremes but interested what others may think.

I know 300 dollars for a bump from C2D/4670 to a i5/4850 is easily one of the best upgrades Apple has offered in a long, long time.... but would I really need it?
I was primarily going to be using the iMac for everyday stuff (word/browsing/etc) and for games occasionally by others. I don't need everything running on ultra with AA on or anything, just visually comparable to PS3/X360. I will be doing a lot of Photoshop/illustrator things as well and might get into video editing.
I was thinking maybe I could hold out on going quad core for a couple years until Macbook Pro lines get it at a reasonable price then I can just use the iMac as a gorgeous led and media hub in the background as I do my work on the Macbook Pro.
I've seen the benchmarks, but how does it work out in real world situations?
What would having Quad cores do for me except help me handle files/render a few seconds faster here and there? I'm sure it's a tremendous boost in things like encoding but how would it help when it comes to image editing?
Is the 4850 a huge bump in specs compared to the 4670? Is the performance gap similar to going from 9400 to the 9600?

So my new ZR30W showed up today.
I had bought a Dell U2711 last week and my wife has a 27" Late 2009 iMac so figured this is a good comparison.
Her iMac has the yellow tint issue, Apple shipped out a new i5 last night so we'll get it next week. Still for the color issue the iMac monitor was fantastic to look at.
I bought the Dell for my MB Pro because of the yellow tint issue. Really the new 27" CD is a great deal because not only is it cheaper but the integrated charger for the laptop is a big deal since they are $80 by themselves.
This is all just my opinion, no real measurement but I do have a Huey Pro and I let it do all the work on each monitor.
Off the top the Dell is the worst of the 3. Considering its close pricing I would not even consider it after seeing the other 2. The anti-glare coating was very difficult to look at. It was either too bright or two dark. My eyes hurt after looking at it for a while.
Color quality I can't really comment on because I have nothing to measure with but uniformity was great, I can say that. It did not have the POP the iMac monitor has.
The ZR30 out of the box was much better. The Dell you could really tell it had antiglare on it, the HP its a much finer finish. Text is clear and the color is great.
Now the bad...it buzzes/hums...bad...I'm sure I just got a bad unit...and it has the yellow tint, right hand side...its not bad.
If I chose Apple RGB for color correction I can't see it at all. But doing the tint test it is perceivable. Its way better than my wife's iMac though.
I got 5 years of on site HP service so I'll just call HP and they will come out to look at the buzz/tint issue. The tint is SO faint but I can see it, and can only see it when I have something full screen.
If I put 2 windows up side by side its very hard to tell but 1 window you can see the gradient change.
So given that the HP and iMac, and I assume 27" CD will have the same issue I'd say get the CD unless you need the extra res.
I plan on keeping the HP for a few reasons. One is I need the extra res, doesn't sound like much but I don't do photo's or video. I spend all day in RDP sessions for customers so every last bit of screen real estate is important to me.
If I didn't need the extra pixels then I would have waited for the 27" CD. The Dell IMO is not even worth looking at. It has its own little quirks and holy crap did it get HOT.
So a first for Apple, they make not only the best monitor for its class/usage but also the cheapest
One other bad thing about the HP, and this isn't HP's fault, my brand new 2010 MB Pro 13 inch struggles to keep up with the higher res.
At 2560x1440 it was a little sluggish opening/closing windows as far as draw speed. At 2560x1600 its bad...windows opening from the dock is very sluggish.
I'll have to try in clamshell mode and see if its better.
BTW I'm using a mini-DP to DP converter right now but will be ordering a 6' mini-dp to dp cable. I ordered a 3' thinking I could get away with it but it doesn't reach. $8.00 at Monoprice and it works perfect.

I am trying to make a decision on what computer to buy... I am buying this computer mainly for graphic design so the screen is a very important part of this decision.
It is between a Mac Mini:
2.26 GHz Processor
4 MB Ram
120 GB Hard Drive
NVIDIA GeForce 9400M graphics
3 External Hard drives: 1 as my main HD, 1 as a backup, and 1 to bring back and forth to school.
With this monitor:

or
24" iMac
2.66 GHz Processor
4GB Ram
640 GB Hard Drive
NVIDIA GeForce 9400M graphics
2 External hard drives: one as backup and one to bring back and forth to school
My main question is what are the specs on the 24" iMac screen such as panal type etc. and which screen is better: the iMac screen or the HP screen linked above. Remember I'm going to be using it primarily for graphic design.

Not to sound like too much of a tree hugger or anything, but I was wondering if anything has changed with the new models from an "environmentally friendly" perspective? I didn't save a screen shot of the tech details for the old models. Here is the environmental specs of the new models.

I don't mean to start a new Thread but I think this one could really pinpoint the problem if we could get some good feedback on this. What is the Common Denominator (besides having the HD4850 option) that could be causing the lockups that some people are having.
Examples Is everyone who is experiencing lockups :
1.) Installed Boot Camp and using Windows with this HD4850 option?
2.) Do you use Safari exclusively and not FireFox?
3.) Does it happen only when Surfing ?
4.) Does it happen only when playing a certain game like WOW?
5.) Does it happen only after you been using the iMac for a few hours?
so on. . .
See my point? Write down or make yourself notes to as what you were doing exactly when it locked up? Reply to this Thread and lets figure this out. It will be must easier if everyone could put their situation in this Thread and maybe we can get to the bottom of this.

I just wanted to share what's been going on with my i7 which I received last Friday. Immediately I was curious about what sort of temps I was going to be running so I installed Temperature Monitor. At idle my graphics readings hover around 40C. However, when playing Warcraft 3 my Graphics Processor Temperature Diode reaches up to 84C.
I don't really know what temps are acceptable, I was just wondering what other i7 HD4850s out there are running. To deal with this seemingly high temperature I installed smcFanControl and boosted all fan speeds by 50%. Noise doesn't seem to be proportional to fan speed at these levels so no probs there. Now I run at 64C at load and I am at peace with that.
Shouldn't the OS be increasing fan speed on its own?
Would like to know what you guys think and observe in your i7 machines

Belkin AV360 1080P HDMI-MDP Input Adapter Review.

I finally got a chance to sit down and test out the Belkin AV360. I have seen other people complain of problems with the Dr. Bott and Kanex (note I have not tested either of these, just posting complaints I have seen) products. Well Belkin has really impressed me.
SETUP:
It has a simple setup. Plug in the HDMI cord from your XBOX, Playstation, whatever into the belkin box. Then plug in the Mini Displayport cord and USB cord from your iMac into the Belkin box. Then when you are ready to play, just turn the XBOX on. Your iMac will automagically know when it is turned on and flip to display the XBOX on the screen. When you are done playing, just turnoff the XBOX and your iMac instantly switches back to the desktop. It really is idiot proof.
VIDEO QUALITY:
The Belkin AV360 does display in 720p. Visual sticklers will probably not be satisfied with this quality when they know that the iMac's screen is capable of more. 720p was fine for me. Definitely could see some pixelation because I was sitting pretty close to the screen which only enhanced the pixels. I was still satisfied because I doubt 1080p would be much better since I was sitting so close.
PACKAGING:
Everything you need to connect your iMac to the Belkin AV360 is included in the product. You only need to supply the HDMI cable to connect the Belkin to your XBOX. This can be picked up for about $3 at Monoprice.
SCORE:
I give this product 4.5/5 stars. The only thing that I would like to see improved is for the Belkin device to be a little bit smaller (stuff can always be smaller right?) and brushed aluminum instead of white as Apple seems to be moving towards the brushed look over the classic white. Those are minor inconveniences and do not distract from the overall experience of the product.
