Is the XFX Radeon 7970 video card compatible with a an Asus P9Z68-V LE motherboard? I'm rather confused with Crossfire and SLI, is it Crossfire allows multiple Radeon video cards and SLI allows multiple NVidia video cards?
So it is possible to SLI with the board and video card I mentioned but not advisable? I'm wondering because I'd be using the cards for hashing so I don't think the PCIe x4 would matter...Dont SLI or Crossfire with that board. It only has 1 PCIe x16 slot. The other PCIe slot is x4, which is very slow.

Thanks - you're right.
I'm not going to bother finding the link, but there's been a lot of testing showing that x4 link doesn't have a very noticeable performance decrease compared to x16, even in high-end gaming. Toms hardware I believe did the tests.
What are these numbers you refer? I checked the wikipedia article and there are versions 1 to 4 but what does mean x16?I'm not going to bother finding the link, but there's been a lot of testing showing that x4 link doesn't have a very noticeable performance decrease compared to x16, even in high-end gaming.

What does it mean to be x16 and x4?No, your motherboard has 2 PCIe slots. One of them is x16, the other is x4.

You can Crossfire two cards with PCIe x16 and PCIe x4, but you cannot SLI two cards in that configuration. Nvidia stipulate that each card must use a minimum of a PCIe x8 slot to enable SLI. If you're running a 7970 this shouldn't concern you since the card utilises Crossfire.So it is possible to SLI with the board and video card I mentioned but not advisable?
