    Edit- Just realized this is totally slanted to VR. For regular monitors, I don’t know... ;-)

    Edit 2 - JDI isn’t shipping 4k displays this month. They are 2160 x 2432 RGB LCD - whatever that is commonly called. Here’s the release: https://www.j-display.com/english/news/2018/20180510.html

    There’s still a couple of things to consider between 9, 10, and 20 series cards. Between 9 and 10 (and above), 9 series can’t do single-pass rendering which can cut CPU loads nearly in half since the CPU only needs to describe the scene once. In CPU bottlenecked apps, that can make a big difference.

    Between 10 and 20 it’s a little more muddy. True, the regular performance difference isn’t huge but it is there. If you need the extra performance, the 20 series has it. At least some of it. But there may be a bigger difference soon.

    The upper 20 series models have VirtualLink ports. Japan Display announced they would be shipping (not) 4k displays in production quantities late this month. This may or may not have anything to do with Valve leaking photos from last summer of a headset in test with JDI stickers on them. You can’t push 4k images at 90 or 120 Hz over DP or HDMI unless you just send low resolution and upconvert. To send it native takes VirtualLink. But at that resolution you also need eye tracking and foveated rendering to make it practical even on 20 series cards. And a year ago, Jensen Huang mentioned RTX cores could do foveated rendering which opens the door to simultaneous high and low res rendering for foveated rendering.

    Lots more questions involved but each level has significant advantages depending on what headset comes out soon (if it comes out soon), what software support it needs and when Nvidia would actually support it, when apps would support it, and what apps you run.

    It’s turned into a tougher question.
