Yes you can use an ati video card in a sli motherboard, however you cannot put two ati graphics cards in that motherboard and run them in sli. As far as putting one in and just running it single your ok. You would need a motherboard that supports Crossfire to run two ati graphics cards together.

For ATI GPUs, it's called CrossFireX. For NVIDIA GPUs, it's called SLI. More info check related links below.
NVDIA SLI and ATI crossfire
The most advanced consumer video cards are the nVidia GeForce GTX295 and the ATi Radeon HD 5970. Most gaming computers will run two of these in SLi (nVidia) or CrossFire (ATi) format, with two on one computer, or even four linked together for dual-SLi.
SLI-ing two different GPUs is a tricky business. Generally speaking, it is not a good idea to SLI different cards as they may have compatibility issues and whatnot. If you wish to SLI, do it with the same cards.
No, the graphics cards have to be the same model.
A gaming motherboard should have at least two PCIe slots for Crossfire or SLI video cards.
It's called SLI (NVidia) and CrossFireX (ATI). Check out "Sources and related links" below for more information.
you dont. you can hook them to the computer though.Another AnswerYou need two video cards in the backplane. Each video card can drive two monitors. The video cards cannot be in their "Ganged" mode (SLI or Crossfire). If they are, only one monitor will be driven (main port on primary video card). The other three will be blank.
