Are we likely to see apple or the third party card manufacturers come up with any more drop in upgrades for these machines. Obviously the current highest card is the 4870, and if you want to dick around there are other options. But I get the impression that apple are getting close to just dropping any major support for efi32 based machines. If it's not likely to see any major video upgrades in the future, would it be worth just offloading the efi32 mac pro and going for something like the i7 machine with the 4850? I know the video card is a little lower, but not hugely so. The possibility of continual video card upgrades is the only major thing keeping me with the Pro at the moment. The current crop of Pro machines are just way too far out of my budget. And I've been moving a lot of my data off my internal hdd's over to network storage. In reality I don't need to size of the pro, I only went with it because at the time the best video card in an imac was appallingly bad.
