Post PCI Express 3.0 video card on PCI Express 2.0 motherboard, will it work? Compatibles?

Hi again guys. Well, I've been searching around the internet for a new video card that I want to buy and I've chosen the GeForce GTX 650. Right now I have a GeForce GT 430 installed on my computer and it works very well but it is a little slow for my needs.
So I'm thinking of purchasing the one mentioned before, the GTX 650 but after reading on websites blogs and other stuffs I have a serious concern about its compatibility (I think it maybe won't use all of it's full capacity) with my ASRock G31M-GS / G31M-S motherboard which uses PCI EXpress 2.0. Am I right about it? What do you people know about this sort of things?

I'm anxious to know your thoughts, you can express your knowledge freely. (No fighting please)...

PCIE 3.0 is backwards compatible with 2.0, the only difference is maximum transfer rate.

Doing the calculations and reading note #1, PCIE 2.0 is all that you need and PCIE 3.0 will not help.

ASRock G31M-GS is PCIe 1.1, not PCIe 2.0-

Chipset - Northbridge: Intel® G31

PCI Express Revision 1.1

I'd assume that calling the GT430 'a little slow' you are using the system for gaming? There wont be any different for normal desktop tasks between a GT430 and a faster 'gamers' card (and the GTX 650 is at best an 'entry' level gamers card).

For gaming there can be quite a difference between PCIe 1.1, 2.0 and 3.0-

I'd save my money for a newer motherboard/CPU with PCIe 2.0/3.0 and a 'real' gamers card.
