Dude, this is the longest running what should i buy thread ever. Just get that Sapphire you linked to already. It's fits your needs. I can vouch for it. I have one. Rock solid, quiet, cool, etc. You can't do much better in price right now, without sacrificing quality.
I revived it to confirm since like I just said, I'm ordering right now....
Since I changed my mind on ordering the 7970, waited for the GTX 780 and 770 to come out and almost the 760, it would last longer. Lots of new hardware coming out right now so choices change.
