Looks like I made a good move.
After living off my last (supposedly temporary) gpu upgrade of an $89 RX-580 just before the crypto mining thing took off, I bought a 3080ti for $750 - 20% cash back a little over a month ago.
I wasn't ever going to pay over $1000 for a card. I wasn't ever going to pay much more than $900 for a nearly god tier 4k gaming experience. The 4090 cost too much, the 4080 looked like an overpriced dog, and I suspected that they'd be hard to get. I expected the AMD 7xxx series to be pretty good and less expensive. They did very well on both counts and I expect that those too will sell for over msrp, and be hard to get.
I'm set for 3-5 years now, whichever way it goes. I'll think about AM5/socket-what4ever, DDR 5 and gpu's when that time arrives.
In the meanwhile, just two 8 pin connectors off an existing power supply since the 3080ti uses less electricity than the 3090 or 40xx series. And they won't melt.
