I have a 27" iMac, 3.02GHz Core 2 Duo, 4GB RAM, and ATI 4670 Graphics Card. I have never really got into gaming on it other than a little bit of The Sims and Football Manager. But now I want to play a few more FPS games like Call of Duty Black Ops. I already have Windows 7 running through VM Ware, but would it be better to have it running through BootCamp. I won't need to use the Mac OS side of things if I'm gaming and if I did then I would just grab my Air. So rebooting to switch OS isn't a problem. With my graphics card, would I be able to run games at minimum 1080? Finally, I use the Magic Trackpad, so would like to use a proper mouse, I'm thinking about getting a fairly good gaming one, would that work ok wired into the Mac's USB port? And same for keyboard? Or would using the standard wireless Mac keyboard suffice to begin with? Thanks.
