Upgrades - 4080 super or 4070 & CPU

[MrMe]

Hi, I currently use a Lenovo Legion for VR Sim racing using the Quest 3:

• AMD Ryzen 7 5800H
• Nvidia RTX 3070
• 32gb DDR4

Unused PC is:
i7-8700K on Asus Prime Z390
(2x8)16GB DIMM DDR4 clocked @ 2666 MHz

Conundrum is to buy a 4080 super or a 4070(something) and upgrade the cpu. Would anyone have any thoughts on this? Instinct is to do the 4080 super with the current cpu, which should yield dramatic improvements for VR sim racing vs my laptop.

You are correct, I did mean the 40 series, long day! (have edited the post)

Modified AC and AMS2, like to push the settings to max and get 90/120hz
