PCI Express 3.0 Graphics in a PCI Express 2.0 Slot

[zessary]

If my friend purchases a motherboard that has a PCI express 2.0 slot and use a graphics card that supports 3.0, is there a performance loss?

Thanks in advance.

After further research, it sounds like there isn't a problem.

Right, you'll be fine. It will fit, it will run. It may not perform the absolute tippy top fastest but it'll be fine.

Your intended build supports PCIe 3.0, but even if it didn't you'd be fine.

I've ran 3.0 in a 1.1 slot. Works ok.

Thanks in advance.

If you really wanna help your friend, tell him not to buy that EVGA GTX 650 Ti 2GB card for $174.99 when he can get a GTX 650 Ti Boost 2GB card for the same money or less.

The new Boost edition card is much faster.

Backwards compatible.

It will work just fine

 

[nightspydk]

No but you cannot prolly run 3,0 in a 1,0a slot and vice versa. Perfornance is fine even 1,0 is is till not saturated.

Tri sli maybe.

yeah I know that's not entirely correct, but the short version. Expect what I'm saying to be true and if not rejoice.

 

[neo.nirav]

As per PCIe specification, It should work. I have PCIe 2.1 card in 1.0 slot. No issues so far.

It should be good to run. There may be a slight performance dip, but nothing that will easily noticeable to the human eye during use (only seen probably in heavy benchmarking suites and even then a few percentage points at most).
