so my mac pro has: 2 x 3 ghz dual-core intel xeon 2gb of 667 ddr2 ram and a NVIDIA GeForce 8800 GT 512mb. And it runs games okay. I know i should upgrade to 4gb of ram but i also wanted to know if there's a better video card to get for the mac side.. OR since i'm running boot camp can i get a windows video card and install it on my mac but only use that card when i'm windows mode and just play games when im in windows? is that even possible? thoughts?
