I started reading up on Eyefinity and got excited. Really think that is the future , for more than games. Certainly a VR world will be more immersive. In any case, grabbed an XFX 5870 and tossed it in the 1st Gen. No workie in OSX, but that was expected. Will have to keep an eye on future OS builds and see when Dev ID = 6898 shows up. It dwarfs even the fullsize 4870 cards. In pic you see it next to an ATI 2600. Makes 2600 look like a USB Dongle. Meanwhile, in Windows it is joy. Eyefinity with the 30 ACD and 24" Dell is rough, really need a 3rd monitor and thus either a DP monitor, or a display port active adapter. I might get the Apple one to check my theory that it is same deal as the Bizlink one Windows folks use. (Will require a DP to MDP adapter, but I think they exist now) More news to come.
