I'm thinking of moving my current 3600X out of my main PC and into a second PC build that I'm currently building.
This would allow me to consider an upgrade to a 3700X or 3800X.
Any suggestions on what is best or should I wait for the next AMD CPU's to be released?
Your question is extremely vague and you don't even say what you use it for or your budget which doesn't realy help anyone to give any advice... have you done some research of your own into the various CPU options?
