But, if you are a benchmarker, every little bit counts.
Didn't you have to apply the patch to get 3.0?

...yes I did...just reverted back to 2.0 to test (SLI instead of Quads), ran 3d11 a few times and compared it to my 3.0 runs...3d11 overall score up by about 70 points due to higher graphics score -but Physics score was a touch lower...also, 3.0 a touch less stable and more finicky than 2.0 (re GPU and mem speed)...not an exhaustive and definitive test by any means, but for SLI, I'll probably stick with 16x 16x 2.0 - for tri-SLI and quad -sli, I'll use 16x 16x .3.0 (you can run the patch executable with ' -revert')...

Well, not just the random difference between runs? That's like 0.3% difference ... is that "statistically significant"? headscratch.gif

NOPE - ...as I suggested , ".....not an exhaustive and definitive test by any means"...

...the only thing exhausted was me, so I had some sleep...just ran another SLI test, and got similar results: overall score up by 80+ points due to graphics, Physics score down by about a similar amount...still not statistically significant, but it does make sense if the patch runs as a background application...I smile.gif

Im certain that there is some sort of bandwidth bottleneck with this mentioned benchmark the OP has posted.
I can guarantee that if both systems ran at Gen3 mode, the GPU score would be matched if not slightly higher on the X79 system.
Especially multi gpu's.

This benchmark is skewed simply because the z78 system has alot more bandwidth than the unpatched x79.
Dont use this benchmark as a reference for your purchase.
