I'm now thinking about it, how one POWERFUL card could last me a while before I have to think about going CF/SLI.

Oh, sorry. Wanted to make sure Poll was correct. Will add to original post.
It's going to be a Corsair or major brand name (going by the PSU guide in PSU Forum). Perhaps Corsair AX Gold. But I'm not sure the wattage; it depends on what card I'm gonna buy. 750 to 1000W.
I'm still not sure on what card I've decided on. I'm debating between the 570/580 and if I go with the 570 I'll duke it with the 6970.
I like all your opinions, thanks. Keep 'em coming...
