... ^^^ right, not sure what the fuss is about as the fastest Tri-SLI Titans score between 6400 to more than 6700 in KaRLiTos table on p1 anyways...whereby Titans probably really get going at higher resolutions like 1440....re scores, just depends how they are cooled, how fast the CPU is clocked at etc.
...but the question of multi-GPU scaling is s.th. I have been trying to shed some light on as I know I'm bumping into the 'rev limiter' of the 1200w PSU with an oc'ed 3970X and quad GTX 670ies (working on a safe, dual-PSU solution next...I reckon the quad score may improve once the PSU question is solved).
So tonight, I ran some test with quad-SLI, tri-SLI and SLI (on a 3970X, GPUs are air-cooled, GPU mem MHz constant for all tests; GPU MHz same for tri and Quad though a bit faster for SLI). The 3970X can go a faster, but as mentioned, with quads, it runs out of juice so I kept it at the same speed for all tests to have a basis for comparison for multi-GPU scaling...btw, I repeated the SLI test with identical settings and cards on my delidded Ivy / same CPU speed, and somewhat surprisingly, it was within 0.2 FPS of the 3970X w/everything the same...both have different strengths and weaknesses, but they seemed to cancel each other out
Here are the three multi-GPU results
(KaRLiTos - this is not a submission... )
