K1r4Production

Just bought a RU7100 last month on a discount and replace my LG UK6340. The RU7100 has excellent low latency. I'd love to buy the UM6900 for the lowest 4k@60hz latency (based on Rting) but in Vietnam I could not find one. Same with some TCL models, they don't import those low latency ones here in VN.

I'm using CrossOver 290M Ultrawide with native resolution at 2560x1080. It's less than 400USD in my country, Vietnam. I've just done an upscale to 5120x2160 using a GTX1070, 200% scaling. With that resolution, you'll have plenty of room for productivity, a lot programs scale well (Adobe Suite, a bunch of DAWs, etc). I have not test any game, but I will definitely run games at 1080p only. The upscale only for desktop use.

As a novice mixing engineer, I'm currently using two monitors, in which one is an ultrawide 2560x1080 and one is 1080p. I'm planning to upgrade to one of these options: ultrawide 3440x1440 for extra pixels and one 1440p monitor; or two ultrawide. I love ultrawide because it make your timeline longer which is awesome IMO It depends on your subjective opinion about ultrawide, however whatever the case (ultrawide or not), you need dual or triple monitors to maximize efficiency. You can have different DAWs or interfaces in different screens, or even within one DAW, there's a lot of plugins which have huge interfaces and will definitely take a lot of space within your screen. 1080p is fine as long as you have at least two monitors, after that you can upgrade later in time for extra pixels. When recording I usually have the virtual mixer (since I don't have a physical one, I cannot afford them at the moment) on one screen and the timeline/tracks on the other. You can have your various visualizers on one screen for tracking your work conveniently

Yes. At the moment everything is fine-ish. I still sometimes have to use some small tricks to lower the CPU load in Ableton due to multiple compressors/FXs on one track (separate them in different tracks and/or use a return track for FXs, etc). I'm sure there are pro-level mixing engineers and music producers out there have this problems even with high-end processors (10-core 6950x or even 12-core Xeon on Mac Pro), that is why they use proprietary products from Pro Tools, Roland, etc, which is extremely expensive. You can check some topics on Ableton forum about those tricks, but R7 right now is the right budget 8-core processor for my level of work. 8 overclocked cores with hyperthread are really efficient. P/S: When I bought my PC, Threadripper was not out yet, and even if it had, I was short on budget. I've planned to buy Threadripper in the next 6 months. Those extra PCIE lanes and DIMM slots is much needed. You can have a bunch of captures cards and other stuffs (extra input ports for synthesizers, sound interface devices, etc) without having to think twice!

I'd suggest Ryzen 1700. I'm using it right now in my new PC for mixing sound and music in Ableton (and few other DAWs, occasionally). Since x299 is a high-end platform (not a good one), and since you have the budget, I suggest go for x399 instead, better future proofing. I'm sure one day you will be grateful for those extra PCIE lanes, even in music production. 1900x for now, and you can upgrade to 1950x later. All those compressors and plugins can be quite CPU demanding, both in number of cores and core speed. And you also need a lot of RAM for playback, as of with anything in the pros world. I owned 32GB of RAM right now, and my work is still asking for more ... You can see my build in my signature I'm a mixing engineer btw (humbly at entry-on-the-way-to-intermediate level)

I have the same problem! Need HELP ASAP!
