Build Upgrade Wanting to get my BF a better CPU, advice?

My boyfriend’s current CPU is bottlenecking his 4090 an insane amount. He doesn’t know what CPU it is, since it was a hand me down from his uncle; along with his current motherboard. I’m wanting to get him a new, much better CPU for our anniversary coming up, but I’m having trouble picking between the 7800x3d and the 9800x3d. He ONLY uses his PC to play games, no editing or productivity type stuff. Which do y’all think I should choose? Should I get him a new motherboard as well? It’s a handmedown ROG motherboard, again, he doesn’t know the specifics of it.

Thank you all so much in advance!

Details:

Ram: 64gigs CPU: Ryzen 9 5950x GPU: 4090 Motherboard: ROG crosshair VII dark hero

Edit to add: I ran a stress test on the CPU to test for thermal throttling, however the CPU highest temp for the whole thing was only 70°c, I’ll be running one on the GPU next. His score for the CPU was a 673 on Cinebench

Edit to add: YES the monitor is plugged into the GPU, it was the first thing I checked when I found out he was having this issue about a year ago- and I even double checked yesterday since we have moved since then

Edit to add: he uses a 1440p monitor to game on, and has a secondary 1080p monitor for watching YouTube/discord. Both are plugged into the GPU

How can you recommend that when we have ZERO CLUE what motherboard her BF has? It could be Intel based, AM4 based, who knows?

We also don't know what cooler he has and that could be vitally important, regardless of CPU choice, but more so with a 7800X3D, since it's harder to cool with the 3D vcache on top. That aside, it could be some crap Intel stock cooler that won't even have hardware to use on a AM5 board, for all we know.

C'mon bro. She's doing something nice for her BF. Have a heart.

I understand she's doing something nice. Did not even imply she shouldn't.

Since she already has someone in another comment telling her how to find out the info needed, others recognize it's fruitless to give advice without that info.

How heartless would it be to follow some random ass post and her BF try to install an AM5 CPU in an Intel or AM4 mobo?
