Hello, My question regards the compatibility of the 5870 with eyefinity and crossfire. I wish to purchase an ATI product due to the high performance and excellent pricing of your product, but there's some confusion about the compatibility of some possible configurations I'd like to do. I currently have four monitors, three of which I'd like to create a display group with eyefinity, the fourth is a secondary monitor. If I buy a 5870, with an active DisplayPort adapter, to accomplish a display group of three monitors, would I be able to buy a second 5870 and crossfire with the first? Can the second 5870 run the fourth display(not part of the display group, just an independent display)? If not, would adding a weaker ATI card just to run the fourth monitor work? Can eyefinity groups be accomplished accross two graphics card, or does it have to stay on one? Can all this be also accomplished with 5850s? I understand that the 5870 eyefinity six editon will have 6 DisplayPort that do not need active displayport adapters. Can this card be crossfire with another (non-eyefinity 6) 5870? The following question regard eyefinity itself: If I have a large central monitor, and two smaller monitors in portrait (such that the height in pixels are very close) can I create a display group? If the height of secondary monitors in a display group is significantly different, is there more option than just change the resolution of the display? (like different scaling options, hidden display areas, etc). Thank you for your help
