I'm about to jump to 7 finally to use the ssd i bought for my netbook properly. The netbook is still starting up fast but now it takes forever to do anything even after the registry tweeks so i'm going to say f it and put the ssd in my game rig with hopefully the right OS. I am not sure between getting 7 home 64 or 7 pro 64. I have a few old games i would like to play like Diablo 2 and up. Do I need the XP mode of 7 pro to be able to play them?And are there any other reasons to shell MS the extra $ for pro over home premium for a reg gamer?
