A little help with my upgrade plans please!

[GunnerBill]

I'm planning on a partial upgrade of my 2017 vintage PCSpecialist PC to boost VR performance for specifically Elite Dangerous Odyssey in VR. Initially I want to replace the MOBO and CPU with:

Gigabyte Z690 AORUS PRO, Intel Z690, S 1700, DDR5, PCIe 5.0, SATA3, 4x M.2, 2.5GbE, ax WiFi/BT, USB 3.2 Gen 2, ATX
Intel Core i5 12600K, S 1700, Alder Lake, 10 Cores, 16 Threads, 3.7GHz, 4.9GHz Turbo, 20MB Cache

Then I hope the costs of chips comes down sometime in the next decade so I can afford to upgrade the Graphics Card!

My question is will that work with the rest of the equipment and should I get a new CPU cooler, perhaps this:
Noctua NH-D15

Thanks in advance

Oh yes and what happens when you fire up the PC with the OS plugged into all this new stuff? I've totally forgotten!

your cpu is old, i have the same, but when VR gaming (I am too) we are gaming at resolutions of 4k and beyond. the gpu makes the most difference in this case so if it's a choice between cpu or gpu upgrade, you'd be better off upgrading your gpu to a 3080/3080ti/3090 nvidia card. your psu is enough for this.

do you know in 4k benchmarks, there's only a 10% fps difference between a i7 7700k and a i9 12900K?

yes at 1080p (typically monitor gaming) cpu makes a big difference but in vr, not so much.
