Pros: Fast, quiet, and runs cool. I've always thought that I couldn't game on a computer with only one graphics card, but when I bought this for my HTPC build, I was astonished, and my opinion has changed. It plays everything I play (Skyrim, Civ5, WoW, and soon Elder Scrolls Online) at maximum settings, and doesn't even cause the fans to ramp up past idle at 20%. This is an absolutely must have card, and I will always buy Sapphire Toxic addition cards when I upgrade or do a new build in the future, and advise others to do the same. Top notch quality card, and top notch heat sink/cooling solution.
Cons: The only issue I have had with AMD cards is the HDMI scaling with monitors. If you use DVI, you will never have issues, but I always have issues with the AMD cards (7950 and R9 270X over HDMI).
Overall Review: I would love to own 2, but you really don't need 2 for gaming at 1080p. Also- be warned that this card is massive- around 13.5" long!- you will need a larger computer case to contain this beast. I also love that it has provisions for more than dual crossfire (usually not available with the HD 7870/R9 270X), which I'm sure will be done over PCI-E in the next generation of these cards, as the R9 290 and R9 290X already have this feature.
Pros: Great looking cards, sturdy build quality, 3GB memory, Crossfire X up to 4 way, PCI Express 3.0. The price I found these at were a steal.
Cons: Not the best overclocker, got mine up to about 970 Mhz core before driver crashes (150-170 Mhz on stock voltage isn't too bad, though). Crossfire x2 seems to have issues with newest drivers, version 12.4. Seemed to run just fine on version 12.3 though.
Overall Review: When crossfiring, if you cannot skip a slot on the motherboard, the top card will hit about 80 degrees C at stock clocks under heavy load (like the Unigine Heaven Benchmark test). The bottom card will overclock fine if you have airspace beneath it, and stay fairly cool overclocked (60-75 degrees C with good ventilation). I believe the HD 7950 in crossfire is a great solution for a single 1920 x 1080 screen with most game settings at high, if you can get a great deal on the cards. If you want to game on high settings with 2 or more screens, though, you may have to upgrade to either 3x Crossfire or 2x or 3x SLI with the Green team. Running on Intel Core I-7 950, Asus Sabertooth X58 MB, 6GB ram at 1600Mhz, 2 of these in Crossfire X (top card at 800Mhz core, 1325Mhz mem, bottom card at 925Mhz core, 1350Mhz mem), single 23" 1920 x 1080 screen. Unigine Heaven 3.0 benchmark at default settings, scored 4120, 163.5 FPS, Min FPS 45.5, Max FPS at 281.3.
