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
None.
You can go out and buy the latest beefy card and within months games will be released that demand more than it can provide. You can try playing last gen games on current hardware to avoid fps losses. But if you want to play the latest releases, you're better off limiting graphical settings to allow good fps.
But in this instance post your specs and what you are trying to run and people here can provide suggestions. But you will eventually see fps drops anyways; that and a lot of games are poorly optimised which results in loss despite bonkers hardware.
