    currently use a 2010 Mac Pro with 6 cores and amd r9 380 4gb for fcpx 10.2.2 video editing - edits raw 4K from a gh4 (100Mbps) fine most of the time with out transcoding.

    May use this in a office so looking for something to use at home for 4K video editing and seeing as I'll need a monitor and the 2010s are so old and rare on eBay I thought of getting a iMac

    Would a top of the range late 2013 with 4gb video memory (GeForce GTX 780M) edit 4K video in fcpx 10.2 ok? Not bothered about the lack of a 5k screen especially if it's £1.5k cheaper!

    The graphics card can according to nVidias website handle 4k playback, but for editing, if I remember right, you depend more on the processor.

    So if the iMac has an i7 there is a good chance it can do some 4k video editing.

    Not sure exactly what you're doing with FCPX but you should be aware that for graphics accelerated workloads AMD graphics cards tend to be a good deal faster. While the 780M is a great card (for an iMac) for its time, and still holds up well today, I'm not sure how well it would hold up vs a desktop R9 380 in FXPX. I would recommend you evaluate your use case and look up relevant benchmarks to make sure the iMac will meet your needs before purchasing.

    Within fcpx I am editing footage from a 4K DSLR - this shoots uhd at 100mbps h.264.

    Edits are fairly simple - web videos of a presenter talking to camera or events. Sometimes I transcode if adding a lot of effects but generally my Mac Pro 5,1 with amd r9 380 handles everything really well and it's great saving transcode time.
