Crypto is no longer mined commercially with GPU type compute. When ETH switched to PoS, it decimated the entire GPU mining industry. It is no longer profitable. The only people doing it now are hobbyists.
Sure, but you can get (much) better price-performance-power out of a CPU which isn't approaching a decade old, when mining ASIC and GPU-resistant cryptocurrencies like Manero. I don't know it'd be worth the effort to buy E5-2697-v4 CPUs which are running in such a specialized configuration over and above AMD Ryzen or EPYC CPUs in commodity, inexpensive mainboards.
Monero is one of them.
