[SOLVED] Can I upgrade my 6yr old build to a Geforce GTX1660 6GB GPU without also replacing mobo/cpu/psu?

Dec 15, 2020
Built my old rig 6 years back, been using PS4 for a while , but now looking to get back to PC.....

If I have to replace Mobo to handle new GPU, then advice on Mobo which is compatible with AMD FX8350 and GTX1660 would be great, and I'm really hoping my PSU is still usable... don't really want to start over completely ...
