I know there are several similar topics on this already, but I feel like I have different needs than some of the other users asking the same question. I am attracted to the new iMac because they are beautiful computers and it is hard to justify giving my money to either Dell or a sketchy online PC boutique. The reality is I have to have windows, but I would like to try OSX and it seems that intel macs give the best of both worlds. Money is extremely tight as a college student and I have been saving for the past year. So now it comes down the the question of which quad-core iMac to blow all of my savings on. here's what I'll be using the computer for: photoshop, illustrator, indesign solidworks, rhino, alias studio rendering in hypershot/bunkspeed shot after effects flash? steam, sims3 I'm looking at the quad-cores for some hopefully speedy renders. Shot does support hyperthreading, but is the $180 upgrade worth it when every penny counts? Thanks for any insight you may have.
