Two 7770 vs gtx 660

Are two 7770 better than one gtx 660? If so is a 620 watt psu enough?

Thanks for suggestions,

  1. Yes a 620 watt is more than enough, and 7770s in crossfire would compete with a 580, IIRC a 580 is better than a 660 if you want to use AA but other than that they perform very similarly.

    IMO go with the 660 and then sli down the road.

    ^^ What he said =) ^^
  4. do you already have a 7770? if so then get another one, if not go for a more powerful single card rather than a cf setup.
  5. I don't have either right now so I will just get the 660
  6. I would also consider the 7870, it's a solid GPU as well.

    I think a single card would be your best bet, at least for now.
  7. if you wanna to buy graphics card..

    always go with the single strongest card that you can afford..

    then crossfiring/SLI-ing it in the future when your card cannot deliver decent frame rate..

    Well, multi gpu always be a last option..
