M395 2GB and M395X 4GB - How much of a difference would it make with video editing?

    Just playing about with configurations and looking to save money where I can.

    How much of a difference is there between the 2GB M395 and 4GB M395X R9 cards? If I went with the i7 4.0GHz on a 5K iMac and a M395 2GB instead of a M395X 4GB would there be a huge difference in how it all handles FCPX or DaVinci Resolve, particularly when using 2.5K CinemaDNG Raw?

    handlin RAW footage, you want the most powerful video card you can get. even then, you mght be using proxies.....

    also, you need to put your editing machine into perspective. think about the cost of a single day of shooting. multiply that by the number of shooting days and then think if it makes sense to cut corners on post production equipment? it doesn't.

    There's no such thing as saving money with video editing lol. That higher memory level is HUGE on higher resolution video, we're just now starting to get 4k video and it's going to be standard in just a few years. A few minutes of your time here and there can really add up, if this thing is just going to be used for family videos and hobbiest stuff? Then yeah it might not be worth it. But if it's in any way going to be paying bills then get the higher vram bro. :D

    Does the VRAM really matter? I know it benchmarks just a little better, but would the added RAM make a big difference for video?

    Is it the vram, or is it because the M395x is a better more powerful GPU? I thought it was the latter.

    4GB is needed for 4K as the bare minimum, 2GB is just about enough for 1080p. In my experience though you really need 6-8GB for 4K to have some overhead, but you can only get that on Windows now, but it's no surprise that lots of people are going back to Windows, Apple have dropped the ball in the past few years.

    All that is based on current technology, obviously speed of the ram is the bottleneck and why we need such a big cache. In the future with AMD's HBM stacked memory being 10 times faster than GDDR5, you'll see cards with only 1GB again.

    Evidence? Market share has increased for OS X!

    "As PC sales implode, Apple Mac sales are surging":


    Microsoft is who dropped the ball. Windows 8.x was such an unmitigated disaster that most key Microsoft managers involved with that have been fired, demoted or left the company ahead of being fired or demoted.

    Apple is not perfect and has recently done some pretty dumb things, including El Capitan Disk Utility, removing (then restoring) iOS Camera Roll, iOS Podcasts app unable to play full screen video on iPad, etc. However none of these are remotely close to the Windows 8 disaster. Microsoft is trying to recover with Windows 10 but they lost a tremendous amount of momentum. They are giving away Windows 10 because they are now desperate due to these past foul-ups.

    People don't buy premade PCs, they custom make them, especially the kind of people who edit video. All over Youtube you see custom made PCs that people are editing on and reasons for why people switch back, also I've not heard a single good thing said about Final Cut Pro in the past few years.

    FCP X is often used professionally and the $100 million feature film Focus was edited entirely in FCP X: http://www.apple.com/final-cut-pro/in-action/focus/

    Other TV shows are edited on FCP X: http://www.fcp.co/final-cut-pro/new...he-rescue-gets-cut-on-final-cut-pro-x-for-nbc

    The upcoming National Geographic documentary on the 30th anniversary of the space shuttle Challenger disaster was edited on FCP X: http://www.natgeotv.com.au/tv/challenger-disaster-lost-tapes/

    Tour de France coverage edited on FCP X: http://www.fcp.co/final-cut-pro/articles/1480-editing-the-tour-de-france-on-final-cut-pro-x

    FCP X used in enterprise-scale TV production: http://www.fcp.co/final-cut-pro/art...o-x-in-enterprise-level-television-production

    The upcoming Tina Fey film "Whisky Tango Foxtrot" is being edited on FCP X, as is the upcoming Science Fiction film Geostorm: https://en.wikipedia.org/wiki/Geostorm

    All of these were edited on "premade" Macs, not custom made machines.
