I know , but lets think you are playing a game which requires not more than 4 cores , then an i7 7700 will run at like 3.8 or more ghz and then if i overclock my R7 2700 to at least 3.8 ghz or more , then i will get the same performance as because higher clock speed uses the gpu more and will i get lower temps as well, than using 8 cores at 3.8 ghz that i want to know.
