French site Mac4Ever says that a hands-on look at the machine suggests that it may in future be possible to upgrade the graphic card in the new Mac Pro. We’ve also heard a whisper of unofficial confirmation from an Apple source.

I’m not sure I buy the official Apple upgrade idea: if Apple intended the machine to be that upgradeable, it would likely have made the CPU upgradeable too. But it certainly seems possible that the construction would make it at least technically possible for third-party graphics card upgrades to be made available at a later date.

Graphics work is a key application for the machine. Apple recently noted that a number of professionals had been testing the machine, among them award-winning extreme sports photographer Lucas Gilman.
