" But but but .... PC gamer don't want to upgrade to RTX 2080 and old GPU is enough to play next gen games !!!"
And how does this news change that you will be able to play 4k PS5 and Series X games with "old" GPUs on PC?
And who said PC gamers don't want to upgrade to RTX 2080? Some want it, some want even more and many will be fine to use whatever they have using a resolution and graphics settings they feel good with.
And yes, there will be obviously also some who need to upgrade and everyone upgrades from time to time. Some will this year, some next or in two years...not everyone this year who doesn't already have a 2080.
Heck, what do you believe an Xbox Lockhart would do? A machine much weaker than Series X. Just running Xbox One games or what?
