@OP :
Did you buy those $100 MSI cards? I suppose they use software crossfire, its even buggier than hardware crossfire and heavily dependent on the software.
Yes I did.
It does seem buggy. Coming out of crossfire windows explorer crashes.. but it DOES work.
Sadly I didn't realize they were software xfire only. But they do work. I see nearly double the frames in Battlefield: Bad Company 2 which is totally playable at 1920x1200 4x/2x in 5750 xfire (but not single card).
I paid $109 for 5750 #1, then $99 for 5750 #2. ASSUMING I ever get the rebates of course.
$209 for cards that out perform the $400+ ones. AND 4 displays instead of just 2. Not a bad deal!
