Ordering a new iMac in the next few days as a birthday present to myself. I have a 2007 model that has served me very well. Trying to decide between the base model with max ram and 256 SSD or The next model up with only 256 SSD upgrade as they are equal in price. I will use this computer for music production, web browsing and streaming movies. what would you guys suggest?? Would the higher end graphics card benefit me at all? Also which would you think is more important SSD upgrade or RAM upgrade. I do not want the 27'' Thanks!
