I will be as a 3090 is nowhere near powerful enough to run most modern games with raytracing at 4k120.
The 4000 series cards won't be either, they'll still need DLSS. Roll on cards that can run at native 4k at well over 100fps with raytracing.
I'm still shocked that I can't play Horizon 5 at 4k 120, it doesn't look that demanding. And I struggle to hold 60fps in certain areas of Wonderlands at 4k 100% resolution scale.
4K 120fps path tracing ultra settings probly looking at RTX6000 for that, so check back in 5 years until then DLSS is king
