    Removed because I misread and posted incorrect advice.

    I'd personally stick with the 5870 for now as it's got plenty of grunt, and wait for the new GPU's at the end of the year :) That's my plan anyway, as my 5870 isn't struggling with anything...

    480 Watts? For a single GTX580? You must be joking.
    http://www.bit-tech.net/hardware/graphics/2010/11/09/nvidia-geforce-gtx-580-review/8
    http://www.bit-tech.net/news/bits/2010/11/15/nvidia-gtx-580-power-limit-bypassed/1
    ~360 Watts for the whole system including GTX580 under load as seen in bit's review is much closer to reality.

    An 850W PSU is the 'safe & sane' capacity to handle two 580s in SLI that I've seen recommended here and elsewhere, so 700W is more than enough for a single card.
    In any case, the quality of the PSU and its rails tend to be more important factors in practice.

    I'm running the following through my power conditioner at typical gaming load:
    -i7 920 @ 4GHz
    -GTX 580, overlocked
    -X58 mobo
    -3x RAM modules at 1.65V
    -An 18W pump
    -24" CCFL-lit screen
    -22" CCFL-lit screen
    -Two studio reference speakers
    -5.1 speaker system

    Total power consumption: ~420 Watts

    So in short, 700W is more than fine for a single GTX580 and you're not pushing it at all with that rig.
    The quality and efficiency of the PSU are more important factors and as long as the model you linked doesn't suck (I'm not familiar with it) you'll be just fine.

    You're entirely correct matey. I didn't read the smallprint on the consumption graphs. My apologies. Numanoid, ignore me. I just won donkey of the day award!:blush:
