This is a beautiful monitor, but it didn't work with my 5870 video card. Got it for christmas one year, but had to sell it off because of that. Now i'm using Samsung's S27A950D, which I'm extremely happy with.
I have a S27A950D on the way for gaming...the ACD is beautiful, but not fast enough for all the fps I play. Not sure if I'll sell it or keep it for text/work use.
My two 6950's have display port...hopefully they are fast enough for the S27A950D.
