Which GPU is better for video editing?

[Crosso_7]

I am planning on building an AMD Ryzen 1800x build and overclocking it to 4Ghz with 1.35 Volts.
I hope to overclock the RAM/Memory to 3200 if not to run at stock speed 3000 Mhz.
Now I am stuck at choosing which GPU I really need.

I am using Adobe After Effects, Adobe Media Encoder and Sony Vegas Pro as my editing software.
I am planning to choose the following parts for my build:

MOBO - - Asus ROG Crosshair VI Hero
PSU - - EVGA SuperNOVA 650 G3
CPU - - AMD Ryzen 7 1800X
COOLER - - Noctua NH-D14
RAM - - Corsair Vengeance LPX CMK32GX4M4C3000C16
(I already have a case etc. to build in)

Should I buy a 1070 or a Vega 56?

The video card won't make a big difference in video editing. However CUDA is better supported than openCL. So I'd get the 1070.

With regards to the ram, even 3000 is not a promise. Neither is your CPU being one of the better overclockers. Do try for the moon, just don't be too mad if you didn't win the lottery there.

Thnx on the GPU part.
Could you explain what you mean with the RAM and CPU part?
Are you sugesting to buy another CPU and RAM or was there something else on your mind?

No your parts are good. Not making a counter-suggestion. Just noting that higher than official speeds are not a promise. Meaning some get better results than others. This is the so-called silicon lottery.

The max officially supported ram speed on Ryzen systems is 2667. The ram you have is tested in an ideal environment in which it achieved 3000 (and in the case of your ram, did so at very good timings as well). But when it comes to putting it in your system and hitting 3000 (or 3200), that might be reasonably likely but it won't happen for everyone. Part of the equation is how many sticks you use, what your total ram count is, the ability of your specific motherboard components to work at that speed. For example with LPX 3200 ram on a threadripper build I've done a little experimentation. I can get up to 4 sticks and/or a max of 64gb to run at 3200. With triple channel mode (96gb) I was not able to get stable boots above 2133. I have not tried 128gb because the last package of ram is lost by the shipper. I suspect that with quad channel and a bit of fiddling with stuff, I can get at least a little better than 2133 on 128gb. With a Intel build I managed to get 2666 on 128gb without any effort at all. Just plugged it in and it worked. Again with Corsair LPX ram.

The same is true of CPUs. You got a good cpu and a good cooler. I would personally get the Notcua NH-D15s over the d14, but the d14 is a quality unit. I have one on a 5930k and it does a good job. Back on the overclocking bit. Some 1800x's do hit 4gz. Most seem to fall a little short. Don't be disappointed if you don't get lucky there. But odds are you will either hit you goal or get very close. Maybe get some Thermal Grizzly Kryonaut thermal paste and be careful to use very little... the resulting 1-2 degrees might help you hit your goals.
