XFX FX777AZNF4 HD 7770 CORE Edition 1000MHz 1GB DDR5 miniDP HDMI DVI PCI-E Graphics Cards - My Personal Recommendation

AMD has finally got a winner
I realize these are made by XFX but they use the new AMD GPU the Southern Islands Cape Verde GPU. The XFX card seems like a good chassic around the GPU offering adequate cooling even in cases where there is little air flow.

I got the board mostly to play with OpenCL which is a programming environment to achieve high performance computing. It is not for the faint of heart but the GCN architecture in this GPU allows algorithms that are not intentionally vectorized to run very fast as long as you give it enough work items. Essentially the GCN architecture makes OpenCL programming much easier. There are book sold by Amazon that cover OpenCL. AMD has recently released a new version of what they call AMD APP SDK as a free download for either Linux or Winblows.

The GCN architecture also handles integers well I wrote a program that calculated SHA1 hash values at over 1GB/sec. I also wrote a floating point digital filter test program that was doing close to 300...

Customer review : AMD has won over a new customer
I'll get this out of the way first. This went into my first build with AMD products. After being an intel/nvidia guy since windows 98 days AMD's pricing led me to give them a shot. I was not disappointed.

XFX's HD 7770 is, in performance, about between a GTX550TI and a GTX560TI (and about exactly on par with a GTX 560 SE). This card really makes AA and AF shine, much more so than the 550 TI on my other rig. It's had no struggle running skyrim on ultra and everything else as well (it's my girlfriend's PC, so she doesn't really get many intensive games).

If I had to point out one pretty brutal letdown it's the 128 bit bus, putting it below the card it's supposed to succeed (6770).

Easily overclocked to 1250 core, I hear it overclocks better than reference due to XFX's cooling.
