Hi all, I'm finally ready to not be shackled to my school's editing lab to work on my projects (both personal and school related)! So going to snag a 27" iMac. Very excited. With my budget I can pretty much do 2 of the following 3 hardware upgrades, so my question is what would you "downgrade". Primarily I'm going to be using Adobe Premiere, After Effects, Maya 3D. 27" 3.2ghz - 16gb of RAM - 1TB Fusion Drive - 680MX 2GB gpu Which would you dump? Thanks!
