dad bought me the pc. It came with vista 64 but dad is very stubborn saying 64 bit OS were shit and he refused to let me keep it, so he unistalled vista and put 32 bit xp on. Eh nothing wrong with an i7 is there, its bottlenecked yes, but I didnt have to buy it :P. I have a collermaster power supply, which im assuming comes with the centurion case, ill look into getting that new power supply, in the mean time i took out the other hard drive to conserve more power for games. Also, I think I might either get a 5770 or 5870, any thoughts on this.
