really the RTX 4080 is going to be a sweet spot in terms of performance envelope. that's a card you'll see with some decent longevity, even if it's not being recognized as such currently.
It will depend on the power upgrade offered by the 50XX and the game development studios appetite for more power.
But TBH I don’t see Nvidia able to massively produce a 2 times faster chip without increasing its price again
Meaning, nobody will get the next gen most powerful chip, game devs will have to take that into account and the RTX 4080 will stay relevant for longer time.
Besides, according to SteamDB, most of gamers still have an RTX 2080 or less powerful GPU. They won’t sell their games if you can play it decently on those cards.
The power gap between high-ends GPUs is growing exponentially. It won’t stay sustainable very long
I'm looking to get a 4090 this black Friday, and even with these refreshes, doesn't seem like my purchasing decision would really be affected, unless they're also refreshing the 4090.
