I figure we should have a thread dedicated to this. I'll keep posting new results here. If someone is going to run benchmarks, follow the same format as mine for overclocks. I'll link it to your post which will have your benchmarks. I'll put the top benchmark performance ones in the OP, too.

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:
GTX580SLI_GTX680SLI_HD7970Xfire_3DMark11_Extreme.png

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):
GTX580SLI_GTX680SLI_HD7970Xfire_2560x1600_UnigineHeaven2.1_Normal.png

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):
GTX580SLI_GTX680SLI_HD7970Xfire_2560x1600_UnigineHeaven2.1_Extreme.png

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.

Top Performers:

GTX 680 Single Card

im interested at what is better at eyefinity resolutions with aa and af maxed

is there any difference in performance between portrait and landscape eyefinity?

and can 680s do portrait surround?

Same here. It will take a while to set-up, it'll have to be a weekend endeavor. You don't need AA higher than 4X at these resolutions, though.

is there any difference in performance between portrait and landscape eyefinity?

Probably. Would be interesting to test.

and can 680s do portrait surround?

I don't see why not.

Very nice thread! Can't wait till you get your 680's to compare.

Yeah, tell me about it. :mfp:

Don't forget I also had 560 SLI, 560 Ti SLI, 6870 CF, 6970 Tri-F, and 6970 CF. :P

check out this article. They compare 7970s vs 680s all the way up to a quad and 4-way setup!

http://nl.hardware.i...english-version

Sure looks like a 680 beats up a 7970 1 on 1, but it's not the same story when you start adding cards.

I guess they're all at stock clocks.

Well, my GTX 680's are here, I'll find out soon enough first-hand. :P
