New GPU dilemma for an i7-8700k

[Adrian858]

Hey folks,

I'm looking for input with a dilemma I'm having, here are the particulars.

Current build from 2018:
Mobo: EVGA Z370 FTW
CPU: i7-8700k
GPU: EVGA GTX 1080ti FTW
RAM: Corsair Vengeance 64gb 3200mhz
PSU: EVGA SuperNova 750w P2
Storage: Samsung 970 Pro 2TB
VR: Rift S

I usually go all out and buy a whole new PC every 10 years, with a few upgrades in between, so I'm looking to stretch my current build out as far as I can. Unfortunately, my biggest limiting factor is keeping the Z370 and i7-8700k (otherwise I'd end up having to build a whole new PC), while trying to find a suitable (and worthy) successor for my GTX 1080ti.

I've done as much research as I can, and I'm aware I will not be getting the full potential out of a new GPU due to the CPU being a limiting factor with bottlenecking. So far, I've been looking at an RTX 3090ti (which are extremely over priced, hard to find, and will require a new Power Supply), and an RTX 4070ti (much cheaper, in stock, will work with current PSU). I like the idea of the 3090ti at 24gb of VRAM, but I'm not sure that 24gb would go very far.

Ultimately, I'm hoping to find a reasonable and balanced solution for a GPU that would hold me over for the next 4-5 years while working well with an i7-8700k. Another reason I'm trying to max out my current specs is to support the Quest 3, once I know more about the specs when it releases, if it will even work (but these might just be high hopes).

Thoughts?

Forgot to mention, but I’m currently on 2560x1440 resolution if that helps anyone offer some advice.

I'd stick with that combo and wait.

The 1080ti is good enough for 1440p, using it myself. Sure, you could up the LOD with some more GPU power.

Replace the 1080ti when it dies, that's what I will do.

I have (had possibly?) this exact combo; i7-8700k with a 1080ti that was running great.  Ended up getting a deal on a 3080Ti awhile back and put that in; I was running just fine with my Rift S or flatscreen. Just tonight my primary NVMe drive just bit the dust…I’d added a second NVMe and a few spinning drives, but I think I’m finally using this as an excuse to do everything.

I've got a 8600k and upgraded from 1070ti to 4090. Man what an upgrade. I am only running a rift s but i've maxed out settings and getting 80fps consistent. I'll upgrade cpu/mb combo next year.
