Sure, with BIOS mods you can get a bit higher performance than what you said. It's a fine/mediocre rig to start mining Ethereum but don't forget that there also other altcoins that you can find and they may earn you more than what Ethereum could in a short term.
Hey, thanks alot for the fast answer. Well I will just start mining Ethereum for the start, as I really don't know anything about mining yet. I will look into mining other altcoins as well. For now I only know what it means, but how to do it, not yet lol. Since this rig is Plug & Play I'm just gonna let it mine Ethereum while I'm learning about other stuff. I will browse forum and read all possible topics about that. Thanks for the fast answer once again.
