So I've been browsing through the various Video card threads and it seems like there's some Mac specific cards being made, some cards that work natively in Mac OS + Windows without flashing the ROM, and some that require ROM flashing. Assuming price isn't much an issue, anybody have an opinion on the "best" overall graphics card for gaming on a Mac Pro 5,1 in both Mac OS X and Windows 7? I really only play BF4 in Windows, and WoW in Mac OS. For context this machine is primarily a photography workstation (3x Samsung SSD and 32GB of RAM). Obviously any card suitable for gaming will continue to function fine in Aperture + Pixelmator.
