Hi guys, I'm going to buy an iMac primarily for music production with Logic Pro. I'd obviously love to get the i5 or i7, but unfortunately those are firmly out of my budget. My budget is £1300, but I was hoping to keep £100-200 of that to put towards the Logic 9 upgrade, so I'm trying to decide between two 21.5" specs: 1) 9400M graphics, 3.33Ghz upgrade. This might leave me enough for a third-party memory upgrade too. 2) ATI 4670 graphics, 3.06GHz, 8gb memory upgrade. Basically, will I regret not getting a decent graphics card? I don't play many games, but equally I'd like this computer to be pretty future proof. Will OpenCL have much impact in the future? Secondly, in Logic would I benefit much from the 3.33Ghz Core Duo upgrade? Or is a shovel load of memory a better investment? One final question: I have a 2007 Macbook Pro that's gone kaput. Will I be able to put its 2Gb of RAM into a new iMac?
