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.System specs:Gigabyte 970A-UD3 MotherboardFX-4170 CPU (quad) @ 5ghz (reached 4.6 effortlessly with stock HS/FAN)XFX HD 7770 1GB (the one you're looking at now)WD Caviar Blue 500gbKingston HyperX ram (would not recommend, 1.65v @ 1600)Rosewill green 630w PSU

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 billion multiply/adds per second.In terms of graphics I also do OpenGL programming and it is the fastest board I have even faster than an NVIDIA board that I got about a year ago at twice the price. I tried one game and it ran fast and looked great but I am not a big game player so do not look at this review for game performance assessment.AMD's Linux graphics drivers finally seem stable and the only issue I had was if you use KDE with desktop effects, either turn them off or select OpenGL as the renderer if you use XRender which is usually the default then OpenGL apps will not update correctly.Bottom line great board for a great price esp if you want to play with OpenCL.

So far I have been running this GPU and it has worked great! It doesn't make my case very hot. I can run GW2 at ultra settings and still have decent frame rate.
