Avid Media Composer - consumer GPU support

So I'm in the process of planning a video editing PC rig for my wife as a gift. She mostly works in Avid Media Composer, so performance in that specific application is the main focus. She'll be editing 4k video, mostly shot on Sony A7SII cameras. My budget is far from unlimited - It's not fixed (yet), but I doubt I'll be able to stomach more than $1600 (equivalent, I live in Norway, so around 15 000 NOK).

If you need price comparison sites, I use Prisguide.no and Prisjakt.no.

This won't be built until AMD Zen is out, as I understand higher core counts are always better for this kind of work, and I want to see how it compares to X99/X299.

From reading around a bit, it seems Avid does support some GPU acceleration (although what exactly is accelerated is more difficult to find documentation on), but the only "qualified" GPUs are pro-level Quadro (various wildly expensive and/or underpowered models) and FirePro GPUs (all outdated, 2014-era). AMD has just launched the Radeon Pro line, which I'd reckon will receive Avid certification soon (if they don't have it already). While the price/performance of these is far more palatable, they're still around 3x the price of consumer variations of the same cards, all while packing inferior (and probably noisy!) single-slot coolers.

I've seen guides online for modifying the approved GPU list to allow for "unsupported" Quadro GPUs, and some GeForce GPUs as well - which frankly seems almost too easy. At the same time, I'm curious as to the VRAM requirements of workloads like this. I know professional GPUs typically have around 2x the memory of consumer GPUs, but my impression is that this is mostly for various complex computational work with huge datasets. How much VRAM does video editing require? If the requirements are high, that pretty much removes any Nvidia GPU below the 1070 from the equation (although the 1060 6GB might be sufficient?). AMD cards on the other hand have more RAM, and as such I'd reckon for example an RX 470 or 480 8GB would be very decent options (very similar to the Radeon Pro WX5100 and WX7100, just higher clocks and a few more cores in the 470 v. the 5100).

On the other hand, none of these consumer cards support pro-level drivers - which I'm guessing applications like Avid might rely on?

So my questions:
-Is it possible to get this working relatively easily with a consumer card?
-If so, how much VRAM should the card have?
-If not, what kind of performance gains are we talking considering the significant outlay for a pro-level GPU? A WX7100 would consume ~half our budget alone, a WX5100 or Quadro M2000 (hah! a GTX 750!) around 1/3.
 
According to this:

http://www.avid.com/media-composer/specifications

Minimum recommended for 2K+ video is Dual 6core or higher. High framerate is even more. Also, the high framerate 4K is the only place they indicate video cards.

I think you are going to be hard pressed to get anything that will work well for <$1600. Probably want to look at dual socket Xeon or AMD systems. Also, what are your storage needs?

Where are you getting the software from? It is $1299, though they have a cheaper education versions for $299.
 
I've seen that page, the thing is that they list "Dual X core" for PC, while the Mac requirements accept single-CPU setups with the same number of threads through HT (probably due to there being no dual-CPU Macs for quite some time now). In other words, I'm thinking an 8C16T Zen (if it lives up to expectations) or Skylake-E should do the trick (or Broadwell-E if the post-update price drop allows me to get more cores). It won't be perfect, but I'm well aware that perfect for this kind of work is well out of reach for mere mortals. I'm looking for decent/good enough. The A7SII doesn't record 4k60, so that's not an issue.

Preliminary specs (obviously open to change):

CPU: Zen 8C16T or Intel HDT 8C16T BDW-E/SKL-E
Motherboard: Whatever has sufficient IO. Nothing fancy necessary, just stable.
RAM: 32GB DDR4. Doubt more than that will be necessary.
Boot Drive/scratch disk: Samsung 960 Evo 500GB.
Storage: Dual mirrored (RAID 1) 4/6TB HDDs. Can expand as necessary down the line, or get a NAS.
PSU: Either she'll inherit my (less than year-old) EVGA G2 750W, or I'll find something else good.
Case: NZXT H440.
OS: W10 Pro. Can get this very cheaply, so it doesn't factor into the price.
GPU: Now that's the big question, isn't it.

I know I'm already stretched when it comes to the budget, so I'm looking for ways to expand it. We'll see what happens.

As for software, she has access through work, so that's not an issue.
 
What does she use at work?

You might be able to get an older dual socket Xeon system for relatively cheap, may or may not be better than a newer CPU.

I wouldn't count on AMD delivering with Zen, they have been a constant disappointment for CPUs the last few years unfortunately.

Nah, the used hardware market here in Norway is nigh nonexistent, and buying used (i.e. with no warranty) from another country is out of the question - anything imported adds 25% VAT to the price, as well as customs fees and shipping. Which is why building myself is the only real option. From what I remember, she has some sort of Lenovo workstation at work. I doubt it's dual socket, but I frankly don't know.

But to try to cut through a bit here: you're saying I should, first and foremost, focus on CPU performance, and rather spend more on that than on a reasonably powerful GPU?

Honestly, I don't know, haven't used Avid before, not sure how much GPU acceleration they use, but from their requirements page it seems to me that CPU is more important since they don't list any GPU requirements except for 4K/60fps video.

You might want to find advice from a more specialized forum.
