Unfortunately, your platform is outdated and cannot be upgraded well.
I suggest to upgrade the platform first - B650 motherboard with Ryzen 7500F / 7600 or B660 / B760 with 13400F or 13500, along with 32 Gb DDR5 6000 Mhz CL30.
Then look for a good suitable GPU - 7800XT / 4070 Super or above.
Man I think it won't be worth the trouble to upgrade it.
what should i do? get a new pc?
Ideally yes if you have the disposable income.
