I've been been wanting to install windows via bootcamp for a long time, just to play games. Now that windows 7 is out, I think I have a good excuse to get windows. My question is, what would be the best and cheapest way to get windows 7? I heard OEMs are good, like the ones they are selling at newegg, but I'm not exactly sure if you can install them. I really don't want to pay $200+ for a copy of windows. Can anyone confirm if you can install a windows 7 OEM?
