" But but but .... PC gamer don't want to upgrade to RTX 2080 and old GPU is enough to play next gen games !!!"
On topic RTX 2080 will be cheaper and become mainstream , so upgrading GPU is just natural way for next gen . I believe RTX 2070 super to RTX 2080 will be mainstream and RTX 3060 will be another choice. AMD also planning in bigger GPU with Navi 21, 23 etc. We might see RX 5800 or RX 5900.
New generation new GPU and new CPU. It's time to upgrade or build new one. I am ready to build my new PC with Zen 3.
