ok so the mobo im looking at is pci x16 2.0 and is crossfire capibly
the question is i wana run crossfire with 2 vid cards but most video cards im seeing are only x16 not x16 2.0 is there much of a differnce

PCIe 2.0 is faster than PCIe, depending on which card you are talking about you could see some pretty decent gains. Which card are you going to be using?
 
Both of those cards support PCIe 2.0.

EDIT: My bad the second one doesn't. I would go with the top one anyway.

Wrong, PCIe 2.0 is not faster than PCIe. It doubles the available bandwidth from PCIe, of which most programs out there don't use the max bandwidth of PCIe.

And as I said almost no programs out there use the max bandwidth of PCIe, so saying that PCIe 2.0 will be faster than PCIe isn't true in 99.99% of programs

Yes thats true, but I was just putting it in simple terms. There are benchmarks that show performance increase with certain video cards when PCIe 2.0 is used rather than PCIe. But they are very minimal.
 
ok thanks, so it doesnt matter when im picking a cheep card like this, thats fine then
ok last question with ati can i run two differnt cards in crossfire?

Yes, you can using Crossfire. For example you can run Crossfire with a 3870 and a 3850. You just need to have updated Catalyst drivers. For future reference you can sli and crossfire any cards that use the same core, the newer Nvidia forceware (80.xxx i think) allows this, and the Catalyst v8.2 drivers for Ati.

True I forgot about that, but the faster card (3870) will be clocked down the slower card (3850), if I'm not mistaken.
