I Need Help With PCI-E! :)

[Krispie]

Hi, from what I've read PCIe 3.0 is backwards compatible to PCIe 2.0. My question is if PCIe 3.0 is backwards compatible even further (back to PCIe 1.0/1.1).

I also have another question. I've googled a lot about my motherboard, but on every website it just says that it has "PCIe x16" it doesn't tell me what version it is. Does this mean it has PCIe 1.0?

My mother board:
MS-7613
( I know it's old and shitty but I'm trying to buy a new graphics card first because I'm in more need of that )

I was planning to buy the graphic card:
ASUS ROG Radeon HD7970 3GB GHz Matrix Platinum Edition (Which requiers PCIe 3.0)

I have installed a Sapphire HD 7950 into a friends system that had a first generation PCI-E x16 slot and as far as I can tell it works just fine. Of course there is some bottlenecking with the system being that old but I think that is to be expected. All in all it is still much faster than what he had before and he is very happy with it.
