Here's my old setup (pardon the dust):
The setup is based off of two Radeon 5970's (one HIS and one Sapphire OC) running two Samsung SyncMaster 2493HM's and one Asus VW266H. The Samsungs are using DVI while the Asus is using the mini-display port through this adapter:

So far I am playing the following games with the indicated results:
Dirt 2: random crashing I can't figure out yet (sound?)
Need for Speed: Shift: plays great so far
Team Fortress 2: (some on dual-screen Eyefinity) worked well
