Advice re. Ultrawide Gaming and Streaming build

[PinkCitizen]

Hello there,

My first OC3D post! Would appreciate some guidance on a new build I am planning for 60+fps 3440x1440 ultrawide gaming to support a ROG Swift PG35VQ Gaming Monitor - 35 inch, Ultra-WQHD, HDR, 21:9 Curved, 200Hz, G-SYNC™monitor and to simultaneously stream to Twitch on 1080p60 following OBS resizing to deal with the aspect ratio.

Country: UK
Budget: 3K or whatever is reasonable for the requirement

Further system requirements and notes re. proposed build:
- Build to last the next 5 years. I am still rocking an i7 2600k since 2011! So in 3 years time I could get a Volta Ti and up the FPS on current gen games.
- I would have considered a 1700 Ryzen build but I am concerned about the single core performance in the long term and I am not sure if it could support gaming on the required res and frame rate whilst simultaneously stream on 1080p60.
- Is it worth waiting for CoffeeLake as an alternative for this build? If so, do we know rough ETA?
- I am highly sceptical that Vega single card performance will be eclipsed by the 1080ti. Do we have rough ETA for new GTX cards and based on historical performance would a 1180 likely outperform and 1080ti?
- I could consider an i9 7900x CPU but I am concerned that the thermals will be an issue and it's likely to be an overkill.
- I recognise the ridiculous 28 PCIE lanes limitation of the chosen CPU but thankfully I am not a fan of SLI / Cross-fire.
- I have proposed the i9 7820X due to Turbo Boost 3 performance. Though tbh sound like I will be overclocking that one to 4.8 like in OC3D review video.
- I already have a 1200w power supply and will buy the monitor when it's out.

I would welcome your feedback, I tried to look up a similar build requirements on YouTube and the interwebz but I am hitting a brick wall!!

Thank you

I would keep the 2600k system and make a steaming machine via a capture card.
In that way you don't have to think about drops in performance. And save some money on your system, as it only need to handle gaming. Gamers Nexus have tested the i9-7900X vs Ryzen 1800x, it's worth a look.

1. you won't wan't a Vega with a G-Sync monitor.
2. Get a 1080ti i think it will last longer than you think. I have a 2560x1440, and wildlands is the only game that puts it in the 60-70fps range

Thank you for getting back to me, in a way what you proposed would be ideal but the challenge would be to output the 21:9 render through a capture card to the other machine when the capture card is limited to 16:9. I don't want to drop res or aspect ratio .

I have no experience in the field. But isn't it possible to get a capture card that can handle 21:9? And the the streaming machine can change the ratio before sending the stream.

I'll research the existence of such card. The latter idea sounds rather possible though, I'll look into that if I can output OBS preview into the capture card?!

Displayport is apparently a problem Look at the last post in that thread, that might work

That looks really interesting, I'll investigate that.

How does OBS deal with a 21:9 to 16:9 conversion?
Does it clip the edges or does it put black bars at the top and bottom?

Either seem inferior for watching as a viewer as we'd either not see everything you see or we'd be viewing it at a lower resolution at 16:9.

I would resize the game to with width of the 16:9 so you will have a blank section on the bottom which will be occupied with overlay, cams etc.

Ah right cool.
