so i bought a new computer from frys the other day.
FRYS.comL|LNZXT

everything is fine and real fast. but once in-game (counter-strike: global offensive) it lags a lot. I know the graphics card is a little outdated and will lag a little bit. but this lag here is fucking outrageous. I cant even move around, tried dialing my resolution down and put video settings in-game to lowest and it still does it.
I was thinking its the power supply, it came stock with 480, maybe i need a 600watt? anybody know?
