Okay fam, I'm done with lag. What GPUs will give me buttery smooth VR performance?

I've had my index for a year or two now, I've got both desktop and my beefy AF laptop that I play it on, but both are still super janky. The laptop is actually better for it believe it or not but I still get some hiccups here and there.

I know my bottleneck on the desktop is my GPU, CPU is ready for anything I can pair it with, what's a good one that will never let me see a frame drop again?

Come on I know you guys have suggestions

Edit: since you're all asking here's a list I made some time ago with most of my parts

Ignore the storage you see, i have like 2nvme drives and several SSD's that I didn't list
