I think the 3090Ti is still the best bang for buck IMO
I have bought three of the EVGA 3090Ti (Renewed) from Amazon. Two for my lab at work and one for home ML projects. I think I got all of mine for about $850 and they are now $1100. Has the Ampere engine and can do the mixed-FP (with 16 bit floats) and has 24GB RAM.
