No, the DAG files are too big for 4GB cards. I would not recommend buying new mining hardware as Ethereum is moving to POS, so I would recommend staking instead.
Staking is much colder than mining, the requirement to stake coins for better profits feels almost impossible unless you have some thousands of dollars that you are ready to throw aside for staking, with 500$ worth of coin put into staking you won't make 1$ per day but with a single GPU you will make a bit more, almost 2$ per day.
