P775TM1 - GPU and/or CPU upgrade?

[Ranger Shrek]

I'm upgrading to 32gb RAM (have a stick coming in that is exact same model #).  System has done well for me since around 2008/2009, although I've gone through 4 screens!!

Based on below, what recommendations for extending this system's life.  Would like extra capability to handle some gaming and a 49" monitor better.  I've done some research on 2080 cards, and i9-9900 and seems like there is no sweet spot for doing upgrades for a few hundred vs several hundred with little bang for the buck as well as BIOS upgrades, risk, etc.  Not sure I'm hunting in the right holes.  Appreciate any good pathways in advance.  Thanks! 

Processor    Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz   3.70 GHz
Installed RAM    16.0 GB
Graphics Card    NVIDIA GeForce GTX 1070 (8 GB)

I got an RTX 4080 MXM to work on this laptop with the backlight mod v2 and a custom heatsink from Cicichen. The temps were excellent and performance too. 

 

The 4080 is a big improvement over the 2080 in terms of performance but this MXM GPU costs like 800€ alone. You can get the RTX 4070 for cheaper, for 500€. They are brand new cards with 1 year of warranty from X-VSION and ZRT.

 

The max CPU you can get is the I9 9900K/KF CPU or the Xeon E-2286M (modded CPU). The Xeon is the cheapest option. The I9 9900K/KF are like between 150-200€. Meanwhile the Xeon one is below 100€.
