http://www.macrumors.com/2010/07/22/imac-shipments-running-low-ahead-of-refresh/ is this thread is only for the 21.5" model only? i prefer to have the i7 quadcore configuration becus i do need high end processor and big screen as 27" is ideal for my rendering and graphic project. actually today i just ordered the 27" imac. but the payment yet to be done so the purchased is still hold. but if apple does offer i7quad model same time as those 21.5" as mention above i surely choose the 27" machines if the price isnt much different.. post before: Im a university student. I do architecture, graphic editing and rendering. The question is i want to buy the latest 27" iMac i7, is it worth to wait for the latest release or just buy the current model? I googled and the most said that Apple will released new model in fall, which is late September, or some said they will released maybe a months or two. I need a high end mac (processor n graphic), moreover i needed it urgently before my final project, but if i do purchased it now, the spec of the graphic is quite old 4850 512mb or worth waiting for the ddr5 5x 1g series? The issues is apart from i7 4cores, i need a better graphic card for my 3d rendering and gaming experience. Any advice is really appreciated. Thanks.
