I'm transitioning from FCP 7 to Davinci. Hate FCPX (much as I've tried to use it), Premiere looks good, but you can't beat free so I went to Resolve. Moving from FCP 7 to Davinci Resolve has been pretty painless. Similar interfaces and shortcuts. The biggest limitations with the free version is that resolution maxes out at UHD, so can't output cinema 4k, and h.264 performance is crippled versus the pro version.
Or a ten foot projector screen! Just waiting for 4K projectors to come down in price, then i'll be all over this.
Still use FCP 7 daily. For any flavour of ProRes it's as fast as I need an NLE to be and always up to the task. Used FCP X many times on several projects and I still find it awkward to work with, and always glad to switch back. I just prefer traditional track based editing. Monkeyed around with DaVinci Resolve which looks promising but it doesn't seem fully mature yet. I guess I'll stay on Sierra until someone comes up with a patch.
I was in school right before the shift to non linear editing, so I learned a bunch of skills that promptly because useless, and basically had to teach myself the AVID. Editing 16mm film on a Moviola was pure torture. 35mm film is thicker and can endure the abuse of the machines, but 16mm was forever getting sprocket holes torn up and shredded.
Yeah, no. I make a living with my machine, doing pro work for many, many years. My hack is rock solid stable, less crash prone that the real macs I have bought previously. This is because it takes work to get a system that will boot at all. Don't regret it in the least. I got tired of buying a whole new machine every few years. Now I can just upgrade the components I need. So the savings go into the thousands over time. And hey, I have a separate internal drive I use to boot into windows too.
Building the mac is the relatively easy part. It's getting the software to work smoothly and without bugs that is the challenge with hacks, and OS updates seem to break things. However, once you got your system all tweaked, I've found the hack to be even more reliable and less crash prone than official mac hardware. Nvidia released drivers for the newer pascal cards so you can probably get more bang for your buck with a newer, cheaper card than the 970 or 980.
