I have always been a nVidia person. So i purchased two 8800GT cards the other day to run sli on my new machine, i install them all and realize its a crossfire so my 8800gt's do not work as intended. so now I'm going to install those 8800gt's in my older pc and buy new radeon's to crossfire in a few weeks, so my question is. What ATI card would i be looking at??( something similar in price and spec of the 8800gt).

Cheers
