I got my gtx660 in my Mac Pro the other day and decided to test it out with this game called "outlast". Most scary game I've played by the way. Anyway, I'm kinda anti steam and will avoid using them for games if I can. I ordered a digital Download from GameStop and wouldn't you know it, they sent me a steam download code. Nowhere in the process of buying this code did it say anything about using a 3rd party service to deliver my content. They won't even give me a refund. You suck GameStop.
