My system has 64 bit capabilities (except for the ram which I'd be willing to upgrade) but I'm running in Vista Home Premium 32 bit. I've run many games on it and many, in fact most, run flawlessly. 32 bit itself is working out but for the purpose of getting the most out of my system, I am considering upgrading to Vista Home Premium 64 bit. Would this inhibit any of my 32 bit games? Can 64 bit emulate 32 bit drivers well? Should I just stick with my 32 bit Vista for my 64 bit apps?
