Will 660ti SLI gain much preformance running at pci-e 3.0? Tags: CPUs Intel i7 SLI PCI Express Last response: December 17, 2012 2:21 PM in CPUs Share Staji December 17, 2012 1:47:41 PM Hello, I currently have a computer set up (saber tooth p67, I7 2600k, 2x EVGA 3GB 660ti, 16GB 1600mhz memory) would upgrading to a saber tooth z77, I7 3770k bring me any benefit?

There's a chart somewhere on here than shows it will be about 3% difference from 3.0x8 to 2.0x8. m 0 l IntelEnthusiast a c 188 à CPUs December 17, 2012 2:21:38 PM While the processor might give you a small performance advantage of maybe 6% (I would say that it isnt worth upgrading). There is almost no value in going to PCI-E 3.0 at this time as even things that say that are using the extra bandwidth are not. m 0 l Can't find your answer ? Ask !
