building machine for svp and madvr, please help me decide

RX480 have issues with madVR (performance, coil whine). I would wait for madVR users feedback before buying an AMD VEGA card.

If he gonna play games then Radeon + Ryzen is not the best choice here. AMD GPUs always need faster processor for not being CPU limited than Nvidia. So if someone want Ryzen but still going to play games then the best way to go is Nvidia + Ryzen. The only reason to wait for Vega here is to wait for price drop on Nvidia cards.

- What benches? 4K gaming maybe. Because all review "benches" show Ryzens fps level at 80ies with embarassing 60 on Gears of War. So if by that you meant "never scratched for 60Hz gamers" then yeah, but I consider 100+ fps preferable which Ryzen can provide only for some games.

Shadow of Singularity much? Anyway, Async compute has nothing with CPU because that is a graphics type of calculations. Also this statement isn't backed up by reality where Ryzen+Nvidia = more fps than Ryzen + Polaris/Fury.
Here you go one video proof https://youtu.be/7NCHhn0xEmo?t=9m24s

Fanboyism. I know that sounds logic that 8 core brings higher min fps but unfortunately reality brought us parity: some games have way higher min fps on Ryzen while others have that on Intel. I know this because I also hoped that theory to become truth but then faced graphs of other games.
I used reddit, watched Hardware Unboxed channel, sometimes Linus or other recommended videos about Ryzen (Ocing, gaming, OS comparisons, etc).

I won't argue on leaks nor take them very serious anymore. Only real reviews.

Also won't comment this because I never said to go with Intel if someone wants best SVP results.

im back again. thanks for all the feedback though never id been more confused after reading all those jargon than before asking the question.
so i decided to go the easy route and choose i7700k with 1080ti .
initally want to build an itx, but the gpu is 325cm length so a standar atx for now

AMD's older "large" GPUs (Fury, 390X, 290, 280X, 7950, 6970 etc) are all great for MadVR relative to their price. They have more raw shader grunt than their gaming-equivalent Nvidia (and AMD) counterparts, which is exactly what MadVR needs.

Vega should fall into that same category, theoretically. Though that's kinda overkill, as a Fury is easily enough for current displays.

I have the 43" Sony X8000D 4K TV and I've used monitors before, but ever since I have switched to TV's it has been a much better experience.

If priority of the PC is competitive multiplayer gaming, go with a 144Hz Monitor.

If the priority is entertainment (watching movies and series) + casual multiplayer gaming + single player campaign mode gaming, then definitely go for a TV.

Keep the size around 43" as larger than that, sitting on a PC table and a chair that's 1.5 meters away you don't want something bigger.

You want a 4K TV, that can do 4:4:4 Chroma Subsampling, with 10Bit HDR. Both of the TV's you suggested above have all those features. And the X85D is definitely the better TV, however the smallest size it comes in is 55".

The X80E is the new version of the X800D (also known as X8000D in the Asia Pacific region).

If you're sitting more than 3 meters away from the TV, I'd say go with the 55" X85D.

If you're sitting 1 to 2 meters away from the TV, get the 43" X80E

One final thing, the best thing about the X800D (the older model which I have) is that it came with a VA Panel, while the larger versions of the screen (the 49" and 55") both came with IPS Panels.

The VA Panel has deeper blacks, which is a big advantage. However, the colours get slightly washed out as you look at it from different viewing angles (so if you're not sitting directly in front of it, the colours get a bit washed out), for me that didn't matter at all because I am using it as a monitor, so it's directly in front of me. The IPS Panels don't have deep blacks, but their viewing angles are great.

I am not sure if the 43" X80E is still using the same VA Panels as the X800D or they switched to an IPS Panel.

So slightly above this range, you have the Samsung KS8000 55" and the newer KS8500 (which use quantum dot technology) they're better than the Sony TV's above. And if you want true deep blacks, you have to go with an LG OLED TV, but they're very expensive usually (however, they are by far the best, and jaw dropping in their quality). Every time I go to a friend of mine and watch a movie on their OLED TV, I feel like throwing my TV in the bin (even though I really like it). It takes me a day or two to readjust to using my TV again.

Stick to your price range, and in your price range I just gave you the pros and cons.

I doubt Vega would be much faster than a 1080TI in MadVR, especially if you OC the TI a little. It's at least on par, and the TI is faster in games for sure.

Have you tried resetting MadVR's settings to defaults? There are some old MadVR guides out there that suggest really bad/outdated settings. A 1080 TI should easily handle NGU, even at 4K/60 with 1080p input, so it sounds like something is off.

In theory the CPU should have nothing to do with MadVR performance, only SVP performance.

EDIT: Oh, you're at 1440p/144hz? Make sure SVP isn't choking your CPU, that can be alot for it to handle. It's also alot for MadVR if you're forcing it to double 1080p then downscale it at such a high refresh rate.

You should look at CPU and GPU usage during a video and see what's limiting everything.

funnily enough, i never put too much care on temperature, and i found that my gpu runs at 84C, the maximum that the target allowed. i remember back then it used to run under 70C.
so i decided to put two noctua 14cm ippc for an intake and changing gpus paste.
in total it cost me around 60buck, so its a 740 dollar saved against buying vega.
now i can put svp and ngu together.

cheers
