Unless you are running SLI or Xfire, anything over 750w is kinda overkill.

As for the op, high chance your gpu is screwed. Or, the graphic settlings is screwing with your card. Try turning shadows and other bells and whistles 1 by 1 off. And try again.
This isn't always true. It all depends on what kind of rig someone has. Between my overclocks and my video card, there is a very good chance that 750 may not be enough for me. We don't really know his full specs, but in this case, you are probably right. Either way, one shouldn't skimp out on PSU and should research what they are buying to ensure it is the right PSU for their needs.
