I alway have ran an old version of XP pro. I bought a dell laptop that has XP home. And besides a few tools, I can not tell the difference. I was thinking about buying XP for a PC I am building cause I can not get sp2 with the old version I have. Do you think XP pro makes any difference for Gaming? Or is Home the same thing. Seems like we all used to want pro, but Im not sure why. Thanks for any advice/help. PS Im running 930 intel cpu and intel 975x with crossfire.
