There you go. I thought you needed to use the card for the board. Now your going to say you can use an SLI setup on an ATI board and a Crossfire set up on a Nvidia board. And a Nvidia GPU on an ATI hybrid board and vise versa.

I had thought it was boards that didn't have specific graphic chips that could use both.

Learn something every day.
Funny how all the companies I talk to about a new DDR3 AMD board to go with my Nvidia for cuda was going to pick up the T1090 six core, never bothered to tell me that I could us thier ATI boards. They keep refering me to NVida boards which there are only a couple of. And they are old rehashed chips.
