I was holding out for a new iMac to be released last month. My question - is a Late 2015 model with an i7, 395x graphics and an SSD going to be perfectly fine for editing with FCPX with? My most intensive use case will be multicam editing primarily 1080p content with 3 x video camera angles plus 4-6 audio channels at the same time. Everything else I do will be pretty sedentary browsing, website creation, no gaming although there's a chance I'd install SC2. If I were to pull the trigger on one will I be disappointed with the performance doing this type of stuff? ie is there anything this model lacks or struggles with that FCPX users have been hanging out for? I might move to 4K video as well but not at all likely for at least a couple more years at best.
