I used the Bosgame GVP7600 with my ageing PC and it gave it a huge graphics boost

The Bosgame GVP7600 eGPU features an integrated AMD RX 7600M XT GPU, offering near-desktop performance with the ability to plug in up to four monitors. The GVP7600 isn’t just for graphics; it also adds a couple of additional ports and an optional M.2 SSD storage expansion slot.
