Hey, I'm needing advice... I currently have the previous gen 27" i7 iMac, and I don't know which is better value to go for. The 27" iMac comes to $3,268 US with 4GB of RAM, i7 CPU, 2TB HD + 256GB SSD, and AppleCare. And I'd buy an Intel X25-M G2 160GB SSD to replace the 256GB SSD. Otherwise, the 27" screen is $999. The Mac Pro six-core @ 3.33, 6GB RAM, 1TB HD, 5870, would be about $4k right? Obviously, I'd prefer the Mac Pro, and I'm thinking that would be the better machine to go for as the GPU is upgradable and I wouldn't have to upgrade each year for the GPU performance, not that the 5850M is anywhere near as good as the 5870 1GB though.
