I would probably buy now if I had an opportunity at a RTX-3080 FE at retail, as it should do everything I'm looking for with a *cough* modestly sized PSU. The leaks coming out for the next gen nvidia are insane from the power usage view, but cards like whatever ends up being the X070 and X070Ti could be remarkably powerful, while still working on a 850 PSU, potentially. You have to factor in crazy inflation with waiting to long term, and whatever potential financial crisis fallout that looms from everything going on in the world.
The last new card I bought was a 750Ti and two of those and a HD-7950 3GB are still running in my rigs, so I'm long overdue.
