Summary: I purchased this card in the hope that I could crossfire link it with its twin that was already residing in my Mac Pro Server. Unfortunately, I later discovered that like with just about every card-slot upgrade one can get for this machine, you need to be running Windows in order to unlock its full capability - meaning that crossfire is only supported in Windows in this specific case. Having two video cards in this system will allow the use of up to six monitors though.
Great upgrade from stock card but for my flight simulator more is needed!!

Summary: Purchased the card specifically for my Mac Pro Desktop to run Xplane flight simulators and up to 4 monitors. Much better then my stock graphics card (can run more options) but still can't run max options like I want without it bogging down or slowing the frame rate . I don't believe this was as good as I could have gotten.
Summary: I was completely happy with this card in my machine, i could max out settings on almost all games such as LFD2, Dragon Age, Dirt, etc.. I had a great experience with this card and so will you. Very overclockable if you replace the thermal paste and have proper cooling in your tower.
