1. How much of a drag is using an external monitor for FCPX? I've never used an external screen for video editing, does it hinder the performance that much? 2. If I never use the HDD on the iMacs new fusion drive, does it even spin? I'll never go over the 128gb SSD so I was curious if i'd still be putting wear & tear on the HDD. 3. I've heard the MBPr's have had trouble with the vid card overheating. Would livestreaming gameplay from console or PC games at 2000kbps/720p/60fps or 30fps cause the vid card to get that hot? Or in general would the MBPr's slim figure have issues with that workload? I've heard it doesn't even get warm but I don't buy it, they must have been streaming 360p gameplay. 4. I've heard they're goin to "silently" fix the overheating issues. Is that gonna be a hardware fix or a software fix? 5. Is gaming thru an external monitor a big no-no? I'd keep it pretty relaxed still...good settings/30fps. I feel guilty when the fans on a laptop are loud 6. If I wanna test the MBPr with all these things to see if it can handle it before I consider a maxed 21.5 iMac, would it be a good idea to buy a MBPr from the refurb store, and then switch out for the iMac if I feel it needs more desktop power? 7. If I wanna use an ethernet connection for a more steady feed so there's no dips while live streaming, would that make much of a difference between MBPr and an iMac?
