Hello. I am building a pc with the R7 3700x and a 2060 super. I don’t know which 2060 super to buy. My top pick is the Gigabyte Gaming OC 3x fans. I can also get the FE. My budget is $420 max. But the other thing is, what is factory OC? Will it hurt my gpu life? Can I underclock to whatever I want? This is my first time building so please help me.
