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.
