GTX 750Ti on PCI Express 2.0 (not 3.0) - compatible but how much performance loss?

[The_Analog_Kid]

I'm just not technical enough to know best solution. My mobo has PCI Xpress 2.0, yet I want the best mid-range video card and I'm looking at the Zotac GTX 750TI 4GB PCI Xpress 3.0 card which is backwards compatible to Xpress 2.0. How much performance will I be losing by not having this on a PCI Xpress 3.0 bus? Would I be better off with a 730 GT card which natively runs on Xpress 2.0?

GTX 750TI 4GB, core 1033 MHz, mem 5400 MHz, 128-bit DDR5, CUDA cores 640, RAMDAC ??
GT 730 4GB, core 902 MHz, mem 1600 MHz, 64-bit DDR3, CUDA cores 384, RAMDAC 400 MHz

Will I be able to utilize the extra horsepower on the 750TI - do you have another suggestion for th under $200 range? Thank you all.

yes it is backwards compatible

and about 1% loss max so it's meaningless

there is no performance difference between PCI Express 2 16x and PCI Express 3 16x; also take a look at AMD R9 270, same price range and 30% more performance than 950ti

if you are going to get 750 ti get only 2gb vram as gtx 750 ti has not enough processing power to use 4 gb vram .

and there will be no bottleneck to your card as gtx 750 ti is not powerful enough to bottleneck pci-e 2.0 16x bus. even a gtx 970 can run in pci-e 2.0 with no performance loss

you should look at gtx 960 2 gb it is faster than gtx 750 ti and r9 270x.

performance loss? there is none.
