If i were you i wouldent walk out until he explains to me how :
"ah pc sucks anyways...xbox has twice the power of a PC"
yes i'm not married so i have the time to argue till the next morning
already had an argument with a guy claimed that his friend's FX5200 can run Unreal 2 @1024x768 ,8xAA,8xAF very smooth (
) so this one should be no problem .
