Hello all. I've been looking at the 30 incher from apple and I want to know how well would it do using only 64 megs of vram? Because I want to hook it up to my 17" PB 1.67, but I wouldn't want to close the screen knowing I could have another 17 inches to "my" cinema. I say 64, because the 128 will be split. 30" with only 64 vram seems like too little (even if gaming is out of the question)... Speaking of which, wtf is up with that? Why not split it accordingly? I'm only wondering, I've been looking around for a second screen. 3K seems horribly expensive, but there aren't any other 30 inchers with the same resolution. I may or may not get it, but I'd still like to know. So anyone have a 30 incher on their PB? How well does it perform?
