Good video fella

[@jphorns730]

How helpful are the externals by themselves ?? I have heard when used with a internal they help but on there own not much help at all . What are your thoughts on this ?

that good sir, is a background. A screen saver is something that comes on usually after a set period of time, to exercise the screen of sorts to prevent burn in images.
