Don't really want to spend $100 on a Windows license, so I was wondering how I'd get by with the Mac version of CoD4. I know it won't play as well compared to Boot Camp, but how much worst? Is it worth it investing in Windows?
Barefeats has done some tests on the 9400M on their website for CoD4. Although it is on high graphics at the native resolution, from the looks of the results you'll want to play it at lower settings.
