However, reading one of the reviews, SLI is a problem for one of them, preventing the sound card from working.
"PCIe slots. The problem I have with this board is that the PCIe 2.0 slots are from top to bottom 16/8/4/8.
When I went sli I lost the ability to run my xfi card. Why? Because I couldn't put my 280 on the bottom slot because it's an air cooler dual slot and it wouldn't fit. Therefore I had only 2 options. Put it in the second slot x8 or the 3rd slot x4. Obviously I had to put it in the x8 slot. When I did this my card covered my PCI slot that my Xfi was on. The only other option for a sound card was a PCIe sound card but wait..........nope, the top card in the x16 slot covered that one. SO...........I am now running realtek onboard sound, which in all fairness is working great and I can tell no difference between it and my xfi, but it sill sucks that my xfi is now collecting dust."
