I have a 2008 Mac Pro 8-core 3.0 GHz with a Radeon 2600 HD video card. I want to upgrade to a better video card, mainly to get better framerates in World of Warcraft. Here are my considerations: --I run two 1920x1200 displays, both connected by DVI. I'd really like a card with 2 physical DVI connectors built in, not one DVI and one mini display port. --This Mac is used mainly for work, so I need something very stable, problem free, and well supported by Apple. I can't afford to be down while looking for new drivers or firmware every time OS X updates come out. --High framerates for playing WoW at 1920x1200 at max quality. --Good for native Mac games, reasonably future-proof so that it will run new games well for some time to come. --OpenCL support would be nice. Based on the above, what card should I get?
