Ok here is the deal. I am the proud owner of a 8800GTX (EVGA). I maybe wrong but after reading other threads here I am under the impression that there is now way my old video card will work in my new Early 2008 2.8 Octo Mac Pro (if this is not true please let me know.) So moving on after I sell my GTX what would be a good replacement card I could use with Mac and Win. Please before you ask why didnt I buy a 8800GT when I got my new Mac the answer is: My new Mac was a great present from my wife and she didnt know better and no Im not going to return it (restocking charge alone .) Just getting a 8800GT is the plan now, but before I sell the old I just wanted some other opinions. I will be using my Mac for photography (as the main) and all things Mac. But once in awhile I might have the need to play a game or two. Thanks for the help.
