I was about to get into the hype but while having a 2080 Super with 8GB of vRAM, I rather wait for the bigger 3080 (Super or Ti), hopefully with double the memory size (20GB I believe), and get that instead (hopefully for around 950€ or less). I want to play in 4K even if I have to rely on DLSS (which I also hope more games use it or start to implement because it works just fine).
I played at 1080p since 2009 (on my old HDTV, a Sharp Aquos 47") and hate bad Anti Aliasing so bad, playing at 4K is a pleasure to my eyes (now with my new LG CX6 55" OLED TV). I just need more frames of course.
The amount of memory is the thing now, Horizon Zero Dawn ( a game from 2016) uses 8GB and with the game maxed I can play at 40FPS average at 4K but with some stutters here and there (the game is not so well optimised have to say), and when you see that you think about the future for sure. Playing at 1440p (the right resolution for my GPU, no doubt about it) I have no issues at all with any game for example. But I'm one of those little 2% of Steam charts that want to play in 4K and now is the time for us.
So I'll wait.
PS: Can't wait to see the reviews and the actual gains from previous generation, also if you can use a Ryzen CPU like mine (3900X) to test not Intels only as usually, that also could be very welcome.
