Hello everyone! Thanks in advance for any advice. I'd like to know how the base 15" MBP is compared to a 24" iMac with 2.93 Intel Core 2 Duo, 4gb ram, NVIDIA GeForce GT 120 with 256MB VRAM for things like photo editing in Aperture. Also how would it compare in gaming? I know everyone is talking about how bad the 6490M is, but what is it like in comparison to the GT 120? Thanks for your thoughts!
