How do I know if I have PCI Express 2.0 or not?

I was looking to buy a new video card, and I had my eyes on MSI GTX 570 here, and I was wondering how I can find out if my motherboard supports 2.0 or not.
This is my motherboard here. I bought it with a bare bone kit a while back. It doesn't say whether or not it supports PCI-E 2.0 or not. It just say's PCI-E x16. The video card it came with was I think a radeon 4350, which is 2.0 according to newegg. Is there any way visually to tell what kind it is?

I'm probably being overly cautious I know, especially being that newegg only has 3 regular PCI express cards. But is there any surefire way of knowing what pci version I have?

It doesn't really matter, as PCI-e 2.0 is back compatible with 1.0

So on the off chance that I have only 1.0, that won't put a bottleneck on the power coming from the card?

You have 2.0 16x on the top slot.

If you put a 570 in a gen 1 slot it would essentially half the bandwidth available to the card.

Easiest way to tell is use GPU-Z with a card running in the top slot.

I knew there was a program for that. I've used GPU-Z before, but I couldn't remember the name.

Under bandwidth it says 8 gb per second, which according to wikipedia is PCI-E 2.0. Thank's for the help

Make sure that your IGP isn't selected.

What do you mean IGP?
EDIT: oh you mean my integrated card, no I have the Radeon 4350 selected. the Integrated card isn't even on there.

Ah ok was just making sure.
