Two gigs of the RAM in your computer now would probably be okay for any game out. Coupled with a nice Core 2 Duo and an 8800GTS it would rock any game out. As far as games that are coming out, like Crysis, which is going to be extremly graphically awesome, that ram would be the soft spot of your computer. I just built my computer now and I paid $164 for 2 gigs of XMS Corsair Dual Channel PC6400. Its actually $204 with a $40 mail in rebate, but, mail in rebates are just cash that you get in a few weeks
. I would definatley not want to go cheap on the 3rd most important part of a computer build.
Right now I have an E6600 firstname.lastname@example.org, 8800GTS 640mb, 2 gigs of that XMS ram, and a 600w Power supply and the game I play is Battelfield 2142. With every setting maxed out, my FPS doesnt drop below 90. And Im also running Vista with Direct X 10... (not really sure if that is helping me at all with 2142, doubt it).
Just thinking about it, now I want to go buy another 2 gigs of that XMS
