I (like a lot of people) am waiting for the new iMac to switch from windows. Can anybody tell me how much of a difference I will see in speed when I upgrade from my current system? I'm probably going to just go for the basic 21.5" unless the SSD drive comes way down (or hopefully becomes standard). I will be looking to do some gaming (bootcamp) and photo editing (not pro work). Current specs Intel (R) Core(TM)2 Duo E4600 2.4 Ghz 3GB Ram 232 GB hard drive Windows Vista 32 bit I appreciate no one knows the 2012 iMac specs but lets assume its as the 2011 but with the Sandy bridge CPU.
