I need you help,
I've got a Mac Pro 1.1 (2006) 2x2,66GHZ, 6Go RAM. In first time (4 years ago) I mount a graphic card : Sapphire 5770 1Go, I could play racing games on windows 7 (iRacing, Assetto Corsa, PCARS) in correct conditions but not fantastic (low graphism 60-30 Fps).
Recently I install a new graphic card : Sapphire R9 390 OC 8Go. I hope real better performances but I'm really disappointed… No better FPS, impossible to increase graphism in game.
I don't know for witch reason it does work better like that. Something limit performance ? CPU frequencies ? PCI ? Other ?
I need your help.

I assume you are gaming in Windows, I think this card is not working properly (or not working at all) in OSX.
Your FPS may be limited by your CPU (2.66 on an old CPU is quite slow for gaming, dual CPU may even make situation worse), for R9 390, you should able to have much better graphics. If you can use higher setting (better texture, more AA etc) but still the same FPS, that basically means you are CPU limiting. Not much you can do except lower all CPU demanding settings (less moving object on the screen, e.g. people, grass, etc).
Anyway, this thread should be for Nvidia GPU. You better start another thread to discuss this issue.
