For gaming purposes? I don't think it's worth anything. The 6400 xt gets outperformed by GPUs from 10 years ago. In my eyes it's worth nothing more but e-waste and therefore I cannot recommend anyone buying the 6400 xt for any meaningful amount of money.

Not only that but between unspecified CPU generation and proprietary mobo, I would not be suprised to see that RX6400 limited to PCIe 3.0 with its 4 lanes.

Just as the cherry on top of this pile of e-waste.
