Giving some more thought to this than "I hope CV2 is better and cheaper"...
Currently, *1070+ is minimum to run most games at close to full settings, at full resolution, at 90 FPS.
If we get the usual (conservative) 30-40% generational improvement with GTX 20X0/**VEGA, then:
We could get an average of 16% more width and depth in CV2, for the same settings and same FPS.
We could get an average of 35% ***"better graphics settings", for the same resolution and FPS.
We could get most games up to 90 FPS.
More realistically, more games will get some of each, and a GTX 2060 will probably be generally-equivalent to a GTX 1070 for the same or today-equivalent titles. Lower the barrier of entry, so to speak.
The generation after GTX 20X0 (30X0?) is where it starts getting really interesting. Even with a minimal increase each generation (unlikely; multi-chip GPUs alone seem like a major increase), that's a minimum of 69% better, and a ^conservative max of 2x.
Using 10X0/CV1 as a baseline, that gets us:
An average of 35% more width and depth in ^^CV3, for the same settings and FPS.
An average of 84.5% ^^^"better graphics settings", for the same resolution and FPS.
Almost all games up to 90 FPS.
Probably some split between "more pixels" and "more FPS", with a bit of >extra detail. At this point, a GTX 3050 is probably somewhere between a GTX 1070 and a GTX 1080, and a GTX 3060 is probably, as may be guessed
equivalent to a GTX 2070. At this point, VR games will start to really take off, I think. A bit better resolution will help, but most people being able to hit the nausea-(reducting/eliminating) 90 FPS with their rig will help move VR out of the "enthusiast space" and into the "general gamer space", AKA >>"casual gamers".
By GTX 40X0, with a minimum of +120% and a max of +174% (conservative), VR will be becoming widespread.
Either that or it's Christmas time at ground zero.
* I have a GTX 960 4GB...
** VEGA high-end seems to be between 1080/1080 TI, but no real info at this point. RX 480/580 are slightly better than the 1060, mostly because of 4/3 more RAM, AFAIK.
*** Honestly, I see games topping out in graphics settings at this point; we've pretty much hit photorealistic, and the remaining is filling in holes and extending the pavement, more or less.
^ The sum of the square of the hippopotamus...
^^ Which is even more speculative than CV2.
^^^ At this point, "ultra settings" may equal "more grass way off in the distance." Elder Scrolls VI, whatever it may be, may be entirely delighted. Unless it's in Elsweyr, in which case grass may be scarce. Distant dust/sand?
> Except for things like FPS's and boxing simulators, where there really isn't much to add other than things like sweat droplets and such.
