Looking for used GPU, possibly some warranty left.

Hello, I have recently built up a PC, I was able to manage most of the components new. The only thing I am left with is a good enough graphic card. I don't have a large budget setup for GPU so buying new ones are out of options. I have budget of around 27k, can go little higher based on type of GPUs and their condition/warranty left. I was looking for 6800xt, 3080. Looking for f2f deals.
