Hello, I've been looking all around the internet but i didn't find a good answer.
I have Gigabyte Motherboard, this version "GA-P35-DS4"
This is a print screen from CPU-Z:

Link to the motherboard page:

PS: Im not sure which ver i have.
And i'm thinking of upgrading my Ge-force 7950 GT Graphics card to GTX 590 or 580. Link is below:

Some people told me i might have a problem with PCIe v.2.0 because my motherboard doesn't support it.
That is my question, will it work perfectly or will it work at all?
My PC Details:
CPU: Core 2 Quad Q6600
RAM: 8 G.B DDR2
