Hi All, Just after a bit of advise really. I need to sell my iMac to create some space for my growing family. Currently have the base-model Alu iMac. Spec: 2.0 Ghz Core 2 Duo 4GB DDR667Mhz ram 250 SATA HDD 7200 rpm ATI Radeon 2400XT I think they are correct, it's the lowest of low base aluminium iMacs, with upgraded ram. I'm thinking of getting the MM, how would my iMac compare to the uber-version (2.0, 4GB, 320GB, 9400M 256MB)? My unscientific evaluation: The processor speed is the same (unsure about cache though) Ram would be the same GB but faster on the MM Hard drive would be bigger on the MM but would run slower at 5400 rpm Video - after reading about the 9400M capared to other GPUs, I've come to the conclusion that although the 2400XT is dedicated, the 9400M runs roughly the same, they outperform each other at various tasks, fair to say that? So, what else am I missing, any other reasons I should/shouldn't go for the MM? Thanks in advance.
