You can mine but most likely not with Claymore and not under Windows. Easiest way is to just install Linux and use PhoenixMiner. It will work for another month or so. Then you need to switch out your GPUs. There is a workaround where you can use something called lolminer and when PhoenixMiner will no longer mine past the 4GB DAG you can use lolminer and it will work but at reduced speeds. At first it'll be 95% of regular speed and every new DAG it will slow down.

I think somewhere in March 2021 it will be around 4.2GB DAG and the speed will be like 70% reduced and not worth it. But for the first few dags past 4GB it will not be as noticiable. However right now ETH is not really that profitable as it was during the DeFI days.
