I had a 890fxa-ud7. the patch would install fine and the drivers would work fine. I would only see a increase in frames in heaven benchmark though...i dont fully understand it. tried sli/tri/etc. I would get the performance of a Single card. Maybe i didnt do something right with the patch instalL? Said it installed sucessfully. Best way to test is to run BC2...before and after to see if theres any difference.
