Hi, I'm looking to purchase a mac for Avid and After Effects. I will use it for a purely digital workflow (dslr) and will be moving projects between After Effects and Avid routinely everyday. I don't think a Mac Pro is necessary because I will not be having to break out a broadcast signal for color correction or need any tape based workflow/inputs. I'm looking to purchase the i7 21.5 imac and upgrade the ram to 16gb's via OWC. The ram is mainly for After Effects CS5.5 but will also be using the 64-Bit Avid 6 as well as Pro Tools 9. Pretty much just looking for a confirmation that this is the proper system on a budget.
