I was thinking about snagging an PC for gaming/streaming but I really dislike Windows and I keep hearing about bad issues from all these custom build places. Would a 21.5 inch iMac with a mobile GPU and pretty tight enclosure be able to handle the heat/stress from gaming on a higher setting while streaming at around 2-3mb/s? It'll only be games like Hearthstone, League of Legends, WoW, etc so I feel like the mobile processor would be able to keep a consistent 60fps in most all situations but not entirely sure. The heat issue has me more worried, which I would try to help cut down on it by going SSD. I'd hate to have the fans going full blast all the time either, since this is the main reason I don't stream with my rMBP right now.
