I am upgrading/rebuilding my PC with a new mobo, CPU, video card, and RAM and going from Win7 32 bit to Win7 64 bit. I have Windows currently installed on its own partition and all of my games on another partition. My question is this: Since I'm switching from 32 bit to 64 bit, will I still be forced to reinstall all or some of my games, or will they be fine since they're on a separate partition?
