Best Video card for Mid 2010 Mac Pro
I'm currently running a Mid 2010 Mac Pro with a 5870 video card in it. I feel that it's bottlenecking processes, and want to upgrade it. I'm not looking to upgrade the computer itself, but want to get the fastest video card that I can.
Looking for suggestions, and links if possible to what you know works.
Thanks!
Mac Pro, OS X Mavericks (10.9.4)
