well, up to now, i know i can run rfactor, and apple promote some other games that can be run on mac with OsX or Xp. But i tried a demo of return to wolfcastle (3) and i cant run it cause of a graphic configuration. Probably it can be solve easily, but i didnt bather.
As for rfactor, i only got 2 times in race, after 1hours of racing, some line graphic that were crossing the screen at some place around the track. I must say that i was racing online, with everything graphic at On and Full. My FPS were in the 40's. After droping a little the graphic, no problem occured, and fps were in the 90's. I was getting less fps than other like Bilbo who was in easy 100-150's, but i had to consider that my graphic card was less powerfull than his.
This could be better for you Carrera, but yeah, expensive : an MacPro Tower, Intel Xeon 8 core, 3.2Ghz :
You can run up to eight 30-inch Apple Cinema HD Displays at the same time with just one Mac Pro.
For motion graphics, 3D modeling, rendering, or animation, you’ll need the greater graphics horsepower offered by the NVIDIA GeForce 8800 GT with 512MB of GDDR3 memory and latest-generation NVIDIA GPU technology. Or the optional NVIDIA Quadro FX 5600 graphics card is the ultimate workstation-class graphics card available, with a massive 1.5GB of GDDR3 memory and a 3D stereo port for stereo-in-a-window applications.

But thos are expensive, start at 2 900$ with no monitor.
I use "boot camp", that alow me on start of computer to or run OsX (mac) or run Xp (Pc). This is the safest way to run them. Their is also a software (i was told less stable) that alow you to run Xp on the desktop of your OsX (i say Xp, but you can run whatever version of windows).
Price are (what you see is the computer, no tower, all in back of the screen :
