These are all in systems with an i7 2600K/2700K at 4.9GHz, 4x4GB 1866MHz memory at 8-9-9-24-1T with an AX1200 PSU. Basically clones of each other except for cooling and storage. Only the GTX 680's aren't yet watercooled, but will be sometime soon.
I also threw in some overclocked GTX 580 3GB's in SLI.
El_Capitan's GTX 580 3GB Overclocks:
SLI = 935/1002MHz at 1100mV's
El_Capitan's GTX 680 Overclocks:
GPU 1 = 1146/1700MHz 1199MHz Boost with 1264MHz max Core Clock
GPU 2 = 1116/1725MHz 1169MHz Boost with 1234MHz max Core Clock
SLI = 1111/1700MHz 1164MHz Boost with 1229MHz max Core Clock
El_Capitan's HD 7970 Overclocks:
GPU 1 = 1170/1780MHz at stock voltages | 1290/1780MHz at 1300mV's
GPU 2 = 1160/1725MHz at stock voltages | Unknown
Crossfire = 1150/1725MHz at stock voltages | 1255/1725MHz at 1300mV's (benchmarks higher, but without negative visual impacts, this is as high as it gets)
Starting off, here's how they do with and without Virtu Quick Sync for video encoding:
Here's some 3DMark11 Performance results:
3DMark11 Extreme results:
Unigine Heaven v2.1 (DirectX 11, Shaders High, Tessellation Normal, Anisotropy 16, Anti-aliasing 8x, Full Screen at 1920 x 1200) - I prefere v2.1 since the way I test, it measure the Min FPS more accurately than v2.5 and v3.0:
Unigine Heaven v2.1 (DirectX 11, Shaders High, Tessellation Normal, Anisotropy 16, Anti-aliasing 8x, Full Screen at 2560 x 1600):
Then some results with Tessellation set to Extreme:
Unigine Heaven v2.1 (DirectX 11, Shaders High, Tessellation Normal, Anisotropy 16, Anti-aliasing 8x, Full Screen at 1920 x 1200):
Unigine Heaven v2.1 (DirectX 11, Shaders High, Tessellation Extreme, Anisotropy 16, Anti-aliasing 8x, Full Screen at 2560 x 1600):
That's it for now. I'll do some benchmarks on Dirt3, AVP, and Batman Arkham City next.
I have a 3rd GTX 680 coming, so hopefully that one overclocks better than the two I have right now, and maybe the overclocks will get better under watercooling? We'll see.
