My System Specs

Default PCI 2.0 / Sandy Bridge with new Nvidia cards?

So my build consists of a i5-2500k, and a Z77 motherboard.
So I have my current GPU (550ti) running on it at PCI 2.0 speeds.
I want to upgrade to the new 760, because it has great value for the performance.
But I was wondering if I'm going to get a size-able decrease in power if I run it in PCI 2.0 since thats what my processor allows.

Any thoughts?

There shouldn't be any significant difference in performance as we haven't really saturated pci-e 2.0 speeds for the most part.

I believe Sky even has a review or two that shows the very minimal difference in high end cards between pci-e 2.0 and pci-e 3.0.

I'm running a GTX 780 on my P8P67 and I haven't noticed any performance hit from the older chipset.

I'll have to check that out, When I get my hands on my 760, I'll have to compare my benchmarks with people that are running on Haswell chips and on the new chipset.

NO difference,3570k performs about 5% better than a 2500k for gaming,i got the benchmarks and there is 0.05% more performance with PCIe 3,don't worry about that,as long as your sandy is decent.

The PCIe lanes will not throttle the card.. difference will be from chip lottery, background apps, usual variance and any other difference in hardware but not from PCIe2 vs 3.
