Would Haswell and the new cooling design of the MBPr keep the system cool enough to stream in HD with a laptop? Or would the current system maybe even do a good job? (although I heard Ivy runs kinda hot) Reason i'm asking is that I would like to get a MBPr for video editing, but I also would like to live stream my xbox gameplay to accompany my YouTube channel. I know streaming HD video can be hard on a laptop, but I also didn't wanna buy a base model iMac just for streaming alone. Kinda confused on what I should do, cuz I'd like to stream/edit, but I could use some mobility as well. I want USB 3.0 for editing, so i'd snag the MBPr. The current iMac doesn't have USB 3.0 so that'd be another reason that would be dedicated to streaming only...and maybe movies till they look better on Retina display. If the new Haswell chips are as good as they sound though, might have to adjust my setup next year anyways:/ Anyone have an ideas for me i'm in a weird purchasing spot.
