Hi I have a 320w power supply on my PC and want to run a gtx570 graphics card Straight from my mother board with no extra power supply , is this possible if not what's the best card I could run without the extra power . I'm running a quad core i5 3,10mhz 8gb ram

No. The GTX570 requires a psu with 35 amps and 500w on the +12v
