My experience with the RTX 4080 SUPER using 1440p 240hz & 4K 120hz displays
Its been 2-3 months since I upgraded to an RTX 4080 Super and wanted to share what the experience has been if you're using a 4K 120hz or 1440p 240hz display with this card! Overall, I've absolutely loved it and performance has been amazing.
System:
RTX 4080 SUPER / Ryzen 7 7800X3D / 32GB DDR5 6000 CL30 / 2TB / 750W
Legend:
- 4K 60 Unlocked: No frame rate cap is applied, game achieves over 60fps at all times, in the case of Cyberpunk 2077 this means 75-95fps, and in Alan Wake II this means 80-100fps
- 1440p 240 "VRR" or 4K 120 "VRR": The game does not consistently hit the max refresh rate of the monitor, but its close enough that I prefer to run it uncapped, and let VRR handle the drops. For me to call it "1440p 240 VRR" That would mean the average FPS is within 180-240fps on a 240hz panel. Likewise, 100-120fps would count to me as "4K 120 VRR"
- If "Unlocked" or "VRR" is not specified, the target frame rate is achieved 100% of the time.

Keep in mind, many, if not all of the games I'm running at 1440p 120hz can run at much higher frame rates than that. I choose to cap my framerate in single player games because I prefer consistent frame pacing. I'm using a small form factor build so it helps keep down on noise and temps too.
Likewise, all of the "4K 60" games run 4K 80-90fps, but its not quite 4K 120, or what I consider 4K 120 VRR territory, so I cap them at 60 for the same reason as above, plus I don't mind 60fps in single player games on controller.
Obviously, there are plenty of benchmarks online, but if any of you are considering a 4080 or 4080 Super for a 1440p 240hz or 4k 120hz panel, I hope this guide helps you out!
EDITS: Changed Cyberpunk 2077 1440p 120 to 1440p 120 VRR after further testing. Added DLSS Quality to RDR2 1440p 120 as it looks better than TAA. (Using DLSS 3.7 .dll in RDR2). Switched Horizon 5 from DLAA to MSAA as DLAA has ghosting and blur issues in this game.
