depends really. some newer games are optimized for 64bit, while others do fine on both. 64bit has a wider data stream, and can handle a lot more ram. 32 bit can only use up to 3GB of ram, including ram on the Gfx card. so you would be maxed out with memory with 2 gigs of ram, and a 1 gig graphics card. I'd go for the 64bit machine, personally.
also, 64bit OS needed for 64bit processor support, fyi, if you didnt already know.
