[QUOTE="lazlo, post: 1323806, member: 222581"] [b]Radeon 5770 x2 work in Mac Pro 3.1[/b] I have four displays (20" Apple Cinema, 23" Spectre, 18" IBM and my Panasonic 50" HDTV) connected via two of the Radeon 5770's...and all four work beautifully. Old, but beautiful. I replaced the two 2600's that came with my Mac Pro 3.1 since one (or both) of them began freezing my system a couple of months ago. No particular rhyme or reason for the freezes other than it always happened when some kind of animation was on one or more of the screens; I originally thought it was OS X Lion, since the freezes started soon after the upgrade. Don't think it's entirely coincidence since I started up on another drive with OS X Leopard on it without freezing. But I also never stayed in Leopard for more than a day or two before switching back (only reason I switch is for one of my older 3D modeling programs - EI Modeler never got updated for Intel). Bottom line is it at least seems to be some kind of voodoo with Lion and prob too many displays and a system that is on 24/7. The 5770's seem to run a lot quieter than the older 2600's (fans ran noisily anytime animation was on the screen), but put out a lot more heat. Will post any problems I run into, but if no updates...prob no probs!
