Spec me a gaming laptop (slightly odd use case)

[HangTime]

Requirements as follows:

• Priority is single/lightly threaded CPU performance
• Needs to support MUX i.e. not passing through integrated gfx
• Primary use case is for playing an old OpenGL game at extreme framerates,
• Not too bothered about RAM and Storage
• Big high refresh rate, low resolution, low latency screen preferred
• Budget not a big concern
• Don't need to buy for a few months so happy to wait

I'm thinking the best best is a 12700H or 12900H, but unsure how the 6900HX shapes up in comparison? Paired with a RTX 3000 series. But is there anything coming out the next few months that could move the dial?

This is probably the best option I've found so far: https://www.overclockers.co.uk/msi-...-intel-i9-12900h-gaming-laptop-lt-2fz-ms.html
12900H, 165W RTX 3080, 360hz screen.

GPU is probably overkill, but I don't want to compromise and would use it for some modern games as well.

Let's assume I don't want it for an old opengl game then, and say I want a very powerful machine to handle the most demanding modern games that are poorly optimised for multithreading.
I guess technically, the game is new because it was updated this year...
