Sorry if this is a repost, a quick search and I didn't find anything. The new 5770 and 5870 have 2 mini-displayports and 1 DVI. I read somewhere on Apple's site that you can only use 2 of them, but most of the PC available cards you can easily use all 3. I have 2x20" LCDs and 1x30". I'm currently running the 2600XT and 4870 in my 2008 MP. But when my 2010 MP arrives, do I need to get another card, or can I run all 3 displays (with appropriate adapters) on a single 5870?
