well, what are you using it for? If it's really nothing video card-related, you can save $250 and have the computer in hand ~2 weeks earlier by going with the 7300. I've used a Mac Pro with the 7300 and a 30" ACD hooked up and it ran just fine for what I did (opened a bunch of applications, went to apple.com and loaded up 4 1080p H.264 trailers). You would definitely be disappointed if you tried running games or Motion on there at that res, but anything Adobe or Apple related (With the exception of Motion and Aperture to a lesser extent) should be fine.
