The main game I play is WoW. However, WoW doesn't support Crossfire. I currently have 2 x 6850's in crossfire, but have been offered a 6870 for dirt cheap. Because WoW doesn't support Crossfire, if I install a 6870 will WoW run with the full power from the 6870 as WoW only supports single GPU's, or will the Crossfire bring the 6870 down to run at the same speed as the 6850 thus not being any different to what I have now?
Should have told you that earlier eh? Thats why I got 2 x 6850s to make the performance on the main monitor better. I think im going to Crossfire the 6870 and the 6850 together, but OC the 6850 to the stock performance on the 6870. Also OC my cpu and see if that helps.
well 3.9GHz and 4Ghz are not that different.
if u dont want to go to BIOS just use AMD's software and go to 3.9Ghz.
by the way i suggest u do this:
remove a 6850 and the multi-monitor and see the performance of a single 6850 in a single screen
and tell us the results
