MacBook Pro :: Maximizing Applications In A Small SSD Space?

So, I need a new SSD for my late 2008 unibody MacBook Pro cause apparently the G.skill Titan epic fails working with the unibodies *sadness*.

The Titan I have is a 256GB SSD. Like most people, I've been looking at OCZ (which some say is the best and their performance doesn't drop too much which I didn't think was possible until trim) or the Intel one (anandtech's very thorough article recommends it, and so do many).

Unfortunately, the Intel SSD only has 160GB (though much easier on the wallet than the 250GB Vertex).

Add to that, I'm a video and audio editor as well as gamer >_< and here I've heard of people happy with 80GB and less!

If I were to get the Intel, this would be the first time I'd have to split files. For example, Final Cut Studio takes up 50 GB, but I've read that 47 of those GB you can move onto an external hard drive.

How else would I go about splitting and basically cramming Final Cut Studio, Logic Studio, Adobe Production Premium, Windows 7 (by the time I get the SSD, it would have already released), iLife '09, and a whole slew of high space games such as Neverwinter Nights 2 and both expansions, Oblivion, Spore, Fallout 3, CS:S, and DoD:S with an ample amount of room?

Or would I have to switch out games and have them in one at a time?

Or would I just have to pay 75% more and get the 250GB?
