As ive said in another thread , im waiting on stock for an EVGA 580 gtx. Just wondering something. I know the 580 only needs a 600 watt psu minimum. i have a coolermaster M700 which says on the box max output 800watt. so i know that will be fine. I have heard 2 nvidia 460's aint a million miles off the 580? is that right and is it possible to get 2 cards that wont be too far off the 580 and that can run on that power supply. My 580 still says awaiting stock, its been 2 weeks and ive a feeling im in for a long wait.
