Right now I'd rather buy this Sapphire Dual-X 1Ghz HD7970 is
$380+8 shipping and has a great cooler.
You get Dirt Showdown and at 1 Ghz (BIOS 2 flip) = GTX680 in performance for $90-100 less. Mine stays cool and reasonably quiet in a well-ventilated case despite my overclock. Runs at 70-72*C most of the time @ 1150mhz and VRM temperatures are still under 100*C at 99% GPU load.
This particular model uses 5+2 VRM design with 2 dedicated to the memory. There is also a metal dissipation plate for the memory. This is why this particular card tends to have good overclocking GDDR5.
You also get 1 Active Display-to-Single link DVI adapter in the box which allows you to have 3 Screen 1080P Eyefinity out of the box.
Keep in mind since neither the HIS 7970 nor the Sapphire Dual-X have after-market chokes, there is no guarantee that you will not have coil whine (Otherwise you pretty much have to buy the HD7970 MSI Lightning, Asus DCUII or Sapphire Vapor-X, HIS ICEQ X or PowerColor Vortex II PCS +).
