someone explain this to Me please.I know enough about computers to be dangerous *Like,I know where the key and the gas goes...*. However,as I understand it,when it comes to cores,there is a level of diminishing return.That is to say,that at some point,it doesn't matter HOW many cores You have,You won't get better/faster/stronger performance?I may be wrong and have misunderstood it.I'm trying to read/learn about computers for My own knowledge,and THIS makes little/no sense to Me
