thats interesting about the differences in computer performance. it seems likely though what or how much difference would that make? if i am not mistaken physX is a different compute performance than others.
i ran across this when looking around about core park (of all things):Dedicated PhysX PPU / GPU for Borderlands 2: EVGA GTX 580 SC versus EVGA GT 640
at first the 580 made a decent performance improvement over the 640 but after extended benching the 640 was actually better.
In the extended benchmarks, the GTX 580 SC gave a 20% FPS performance boost to the GTX 680. The GT 640 gave a 24% FPS performance boost to the GTX 680. Interesting…so what is happening here? Well, I did simply play extended sessions – meaning the uniformity of these tests is suspect. However, this does give you an indication that the GT 640 is not that far off from the GTX 580 SC performance-wise when used as a dedicated PhysX processor!
though the 640 is clocked 100Mhz, if we entertain that core speed does make a difference, it has 75% of the cuda core of the 580 (384/512).btw, just a mention of the main gaming card was a 680 with 1536 cores.
btw, it seems this cat loves the 640 for a PPU . . .Dedicated PhysX PPU / GPU for Borderlands 2: EVGA GTX 690 with EVGA GT 640
and the mother of all PPU shoot outs (for kepler)Dedicated PhyX PPU / GPU Shoot Out: GT 640, GTX 650, GTX 650 Ti, and GTX 680 – paired with a GTX 690.
