I disagree that 10-bit is “unlikely”. It’s more of a ignorance of benefits that an unlikely scenario. I get a lot of pro colorist and post house delivering stuff with banding, too much shadow noise and color/gamma problems that have obviously been graded in 8-bit on typical 1000:1 panels. See it all the time. 

Same as I see people mixing on headphones or uncalibrated speakers and charge pro prices for the service. The defense is always the same “looks/sounds great here!”.

 

GeForce cards cannot display video in Premiere or images in Photoshop in 10-bit, period or most any other pro app. You have to have a monitor card going to a separate, second monitor. That card or box + monitor for a 4K setup is not cheap.

 

Quadro cards offer native 10-bit OS level support with Quadros and Mac is now fully supported.

 

Most people think they do don’t need 10-bit output but end up delivering work that looks bad in 10-bit, 12-bit and HDR environments or displays with wider than the 8-bit (and 6-bit+dithering panels out there).

 

DCP is 12-bit. Rec2020 is 10-bit as is all Netflix, Amazon etc. HDR> Hell, YouTube HDR is 10-bit.https://support.google.com/youtube/answer/7126552?hl=en

 

If you’re delivering 10-bit and while it used to be rare, these days almost everything I deliver is 10 bit or higher.

So I just don’t take people mastering final projects for professional deliver very seriously that don’t have a fully 10-bit or higher workflow.

Quadro plus a good affordable HDR 4K 10-bit monitor is the same or less money than a GeForce + 10-bit video output plus dedicated 4K display and offers better drivers, more stability and more flexibility (like Photoshop work).

Thanks for the input. It has confirmed my intuition to stay away from the Quadro and Xeon for this build. Looking at either 2x 2080's or 1x 2080ti now. Don't have funds for 2 of those. :-( 

No need for 10bit output here. Mostly making HD TV promos on this machine.

okay I'm seeing a lot of mixed advice. The problem here is that there is a major real-world consequence of getting the wrong type of processor these days, and it is REALLY important to buy the right system for YOUR workflow

 

The big points - 

 

- Unless you NEED 10 bit color output (unlikely) do not get a quadro. They are intended for industrial CAD / CAM workflows and are 1/10th as fast for rendering CUDA Redshift. They are intended for use cases where you need extreme floating point precision, like designing critical infrastructure. Nobody is using Quadros for Redshift / Octane. 

- The same goes for Xeons. Do not get a xeon system. Many builders try to sell you on xeons because they can make more markup on it. They are extremely expensive and offer little to no performance benefits vs. i7 or i9. This is basically due to A) lack of overclocking ability and B) way more expensive ECC RAM required (not necessary). The large number of cores means each core is slower than the equivalent i7/i9. AE and most tasks in Cinema are still single-threaded. The exception is if you plan on doing a lot of CPU rendering in Arnold (which is going GPU soon anyway), or high end simulation work in houdini etc. 

- Basically - the more cores you have, the slower each core is, this is based on thermal and manufacturing limitations. AMD TR chips are good but the same applies - only necessary for pure multithreaded CPU tasks. 

- Currently, for future-proofing, the only GPU I'd look at right now is the GTX 2080ti - but try to find the "blower" models and not the "open fan" designs, as those tend to just push hot air around inside your case. 

 

I'm not going into a specific parts list but from what you're saying I'd be looking at a system with an i9 chip with 8-12 cores, high megahertz boost / OC abvility (4.2-5 Ghz) very good all in one liquid cooling (a 360mm radiator is essential), and one or two GTX 2080ti's. And yes, RAM prices have blown up and stayed there due to manufacturing shortages, supposedly. 

 

I am currently rocking a machine I built with the core i7 7900X, 4x 1080ti, 128 GB RAM for similar workflows and it does great. I will say avoid Asus motherboards for now, they can have issues
