This was one of those purchases I kept putting off, but the $100 rebate per LCD finally enticed me to upgrade from my previous dual head setup (2 Sony SDM-P234 23" wide screens). All's I can say is WOW...
The 2560x1600 resolution on a 30" display is really something.. and having them in a dual-head config pretty much allows me to fit everything now without any need to horizontally or vertically scroll. I have these monitors suspended/floated over my mixing board and about 2 1/2 to 3' away from where I sit, and the resolution is so precise that I can clearly see every detail even at highest resolution.
As you probably know, these are essentially the same spec as the Apple 30" cinema display, but they cost less and run dead-silent. The other factor is that each display supports 3 DVI-D inputs! Very cool.
Definitely one of those purchases that has me asking... why I didn't I do this sooner!?
p.s. using XFX 7600 GT to run 'em.... easy to get DUAL DVI cards nowadays.
