As a Technical Consultant in the CG industry, I have noticed that a large amount of people starting out in this industry overlook the importance of graphics kit. Seems silly to me. Especially as it is a large part of any visualizer's or 3D operator's workflow.
At the moment, the trumpet to blow seems to be that film and games production are converging. If you believe the hype, we'll be in some sort of nirvana where we all use the same approaches etc to the art of making both.
Apple have made quite a few modifications to their machines lately. Firstly, they've brought back the Quadro. Only this time it’s not the 5600 but the 4800. The only snag with this is that it's a bespoke model, and doesn’t include the 30-bit capability of the PC equivalent cards. Essentially, it is down to the fact that Apple machines require an EFI BIOS from add-in cards, and cannot manage a legacy firmware that is typical of the PC ranges.
