I just bought a new iMac 27" i7 to supplement my 3.5 year old Mac Pro 2.66 Dual Core with 7gig memory. I'm thinking of upgrading to either a new Mac Pro or another iMac i7. I'm a working photographer and use PS CS5 along with Aperture 3 all day long. I have several reasons for thinking of upgrading. My Mac Pro is past its Apple Care though working flawlessly A new Mac Pro would be a lot faster? A new iMac i7 would save me from buying the new 27" Apple LED (plus converter) that I'm looking to buy for my Mac Pro What do you guys think? Thanks!
