Hi everyone. Amateur Ethereum mining researcher here.

I have a question regarding the Ethereum mining process. I wanna know, if we spend a lot of money buying PCs with 5x badass VGAs, how long will they mine Ethereum well?
I'm asking this because, as you know, there was a stage in bitcoin mining process when mining with a high-end PC became obsolete and unprofitable, and only special mining devices like Antminer could have produced decent results.
So, what do you think? Will that happen to ethereum too? Any ETAs? Is this PoS thing everybody keeps talking about result in a change in mining devices?
Thanks in advance.

Hopefully, long enough to make money, which is less then 2 mo for some cards right now.
BTW, it is GPU, not VGA, VGA is a connector

Nobody can tell you because nobody knows.
