My 2009 27" iMac i5 died and has to be replaced. Its my office iMac running the usual mac stuff- mail, net access, under Snow and several PC ONLY businsee apps under Vista/Fusion at the same time w/ shared folders. It's also wirelessly networked as the PC CLIENT TO A DELL server for the PC BUSINESS APPS: accounting, billing, client records, and Xray imaging capture. Since the $1800 base model 27" w/ the 512k vid card, is easily more capable that the rotten apple that just died, is there any point to the $2000 base model, and then any point to upgrading that with the i7 chip, and / or with the 2gig Vid card upgrade? Seems that the $600 price diff can buy an iPad! Thanks.
