oh, just noticed your still on 32bit XP, get a copy of 64bit Windows7 also.
Will that make it go faster for him?
Considering it'll allow him to use all 4 gig of his RAM, yes it will.
You can make 3gb of ram easy if you run crysis on max graphic settings. I only run on high and crysis uses 1.6gb by itself! Win 7 is using 1.2gb so thats 2.8gb usage + what other crap is in background. On very high you would run out of ram.
And x64 does run better than x32, FPS increase isn't that much but it allows the game to use more ram which sometimes have a great effect on performance.
*Edit* This is memory usage with game shrunk so it could be using even more, until I get new keboard I can't tell usuage while running game.
Crysis doesn't need 4 GB of RAM - at best I'd expect such an upgrade to make no difference. If MWLL requires in the 3 GB ballpark, it could, though...
Who cares how much RAM Crysis actually needs. That isn't why I said to get 64bit 7. I said to get 7 so that he can use all 4 gig of RAM the he ALREADY PAID FOR. Also, Windows7 will allow him to use DX10 and beyond. Here's a list of upcoming DX11 games(some rumored, some confirmed true)-
Aliens versus Predator (confirmed)
Battlefield: Bad Company 2 (confirmed) Q1/10
