How does a GTX 780 Ti Compare to 2x 7950s in Crossfire?

Would a single 780 Ti be a "downgrade" compared to a 7950 Crossfire setup? I don't generally have any bad experiences with Crossfire, so I'm talking about raw frames per second. Would a Ti feel like a downgrade from two 7950s?

Thanks!


Bonus Question! Suppose I did swap my 7950s for a 780 Ti and decided to buy another 780 Ti for SLI, would my Thermaltake Smart Series 850W PSU be sufficient? It's 88% efficient with 12V Rail @ 70A.


Thanks!

  1. 7950 CF will give you more fps.

    Yes the PSU will be enough, but it's close... I wouldn't add lots of hdds, fans, etc.

    One GTX 780 Ti doesn't compare at all with two HD 7950s in Crossfire. Two HD 7950s in crossfire crush a single GTX 780 Ti. It's not even close so it would be a huge downgrade.

    BONUS: nVidia.com says that the card draws 250W and the minimum recommended PSU for one is 600W so add 250W to that and you hit 850W. You should be alright.

    I caution you however that your current setup is already so powerful that it can play ANY game at max settings with no problems. Changing your GPU setup would be a complete waste of money at this time.
  3. i am also wanting to know more about this sorry to thread jack. But i want to know if its worth me getting another 7950 to add to the one i currently own which is less than $200 or get a GTX 780. baised on your responses to his statement it seem you would rather leading me in the direction of 7950 Crossfire.
