cant send any of that money my way can ya? no? ohwell worth a shot...
i've read some bits about the 23" version... and a few bits about the 30" version. seems both have some problems with ghosting, and got very negative scores on the blacks, stating there pretty light still. that, and its got a massive native resolution. of 2560 x 1600.. your GT will barely pull any games on that. on the anandtech review of the 512 GTX, the gt manages 27 fps at 2048x1536, without AA.
also, THG had this to say on the 23" model:
"Forget gaming, too. If you're a fan of RTS or World of Warcraft, the Apple Cinema might do for you. But if you like a steady diet of blowing bad guys away, you'd better look elsewhere. This screen was playable, but remanence was very perceptible."

cant imagine it beeing much better at 30". on the plus side though, it sure is a beauty to look at.
