Aha you mean the fx-8350 yes you're right but still long term it would be worth it cpu's live very long nowadays and I think the 4770k is a bit better performance.
But it's really personal preference I have a fx-8350 just a tip buy a cooler otherwise you will feel like you're near a airplane it's very noisy the stock cooler
How many bots can you run on it? Yeah I have a leftover cooler from another cpu and it's really good at keeping low temps

Yeah but to be honest I think botting in wow being profitable will be questionable in 5 years, it's a long time

Probably going to go with the fx8350
