I know a lot of folks like to rip on AMD and their driver support, but here is my experience tonight.
1. Setup 3 1920x1080 monitors
2. Connect 2 via DVI
3. Open Catalyst Control Panel and go to Eyefinity settings
4. Plug in Mini-DP active adapter
5. Configure setup by telling the Catalyst app which monitor was 1,2,3
6. Load Oblivion and start playing at 5760x1080 within 5 minutes
