I currently only have 3gb ddr3 memory (2x512, 2x1gb) and soon I will be replacing the 512 sticks with 4gb each so in total I will have 10. I am putting 64 bit windows 7 on to support the ram, and I just want to know if 64 bit has any benefits other than allowing more memory? For example If I play cod on my 32 bit system with 3gb then play it on 64 bit with 10, is there any reason it would be better other than more ram?
