  1. It will be able to support both cards... Although i doubt you will see an improvement by adding the 560 as a phyx card. But yes it should be safe to try.
  2. yeah it should work, you will see improvements in physix enabled games such as Mafia 2

    You will likely only see a small improvement and only in a very few games. But like I said no harm in trying it out, the extra power draw might not be worth the little improvements that you will likely see...

  5. thanks guys for input my m8 said phyx on gtx 680 buy itself ie single card would be better i don know what to do ??????
  6. It should be fine to try, but it may not do much for you. Do you play many physx games? I'm not aware of many games that have really used physx to any great degree recently; Mirrors Edge was the only big one I know of, other games have minor support but I don't think it's ever been anything ground-breaking. But I've run AMD for the last 5 years, so maybe enabling physx adds some amazing features which I've never seen.

    You would probably see the biggest difference by selling the card (your wallet will have a decent performance increase).

    As others have said, your PSU isn't a problem. You can go ahead and try it and see if it improves physx games for you. Personally, I doubt it'll make enough difference to justify the added power/heat. I'd sell the 560, but that's up to you to decide. You have it so you might as well try it.
