It'll help in the sense you won't be bottlenecked by 4GB of RAM, which can happen I think. As others have said, the GPU in the high end 27" iMac is much better, I'd recommend getting that if possible.i am buying it from OWC and im getting 12 gb total that wont help at all in performance
yes but what your telling me is that if i get the 2000 dollar mac i wont need any and i mean any ram upgrades.
