Personally, if I were you, I wouldn't spend that much money on your comp. Computer technology changes so rapidly - I don't think I've used the same computer for more than three years. If I were you, I'd just buy a dell

Customize and pay the $24 to upgrade for 80GB SATA to 160 SATA
Just buy a system like this, and then get a kick-ass video card for $150 and you'll have a decent system for $675. With the money you have leftover, you can buy another new system in a a few years.
It's nice to have the 1-year Dell support in case anything should go wrong with your computer
I used to build my own computers, but I found that it's almost the same amount of money to buy from Dell - and the best thing is, their computers run quiet (they don't sound like the jet engines I used to build myself

)
