Ha, the benchmark is actually a free download here.
I really hope you have a nice 4k 120hz or 144hz monitor to go with that 4090 or you're just wasting cash, but yeah, no way I can compete with that $1600 beast, that's like an 18 wheeler with nitro turbo jets to my classic sports car.
Doesn't mater that it's free, I can't see the sense in benching with something that has content that doesn't interest me.
As for the display, eventually it will be a 42" 120hz OLED most likely, as I've seen prices as low as $900 recently, and they'll be coming down more. DSR is a pretty good way to get a much better picture if you're on a1080p like I currently am though. At the very least it will be a good hold me over until I get a better display.
