I wonder if I can steal the Vista upgrade disc from my dad's HP and put it on mine. I'm afraid to do it though, Gaming performance is very important to me. anything under 55 FPS really bothers me.
there are always ways to get around this, just get a spare hd, and install it on it, if you don't like it..then you'll have a backup drive. hd's are not that expensive and the price's will continue to fall.
