oh well dude i just bought this GeForce (See Specs below) and i have no lag on CS and i get 60fps on it now. Nothing is wrong with mouse i love wireless optical or at least mine. also when i had my chipset vid card on and eveyrthing i used my wire mouse and it still lagged. so everything is cool now and i love my video card. if i don't need a faster system how come eviltechie said i did? maybe he is just to full of his system.lol.
