I landed the 3080 12GB model, which also has a few more cores and a 384 vs 320 bus for the same cost as any 10GB model. Other than above 60fps 4K, this card is more than enough for just about everyone. It's almost a 3080Ti. Again, these can be found for $750.
At 3440x1440p or below, it will give everything you need for quite a few years to come. I prefer to buy new cards with full 3-yr warranties, and knowing they haven't been flogged by miners.
