OC my GPU

[Lathishment]

Hey, so I just bought and installed a Gigabyte r9 270 windforce and wanted to OC it. I have never OC'd before and have no idea what I am doing. I am using MSI afterburner and was wondering what should I set everything to? I unlocked the voltage and whatnot but I am completely lost. It says it is OC out of the box but was wondering if I can OC it any higher? here is what the current stats are

Power Limit (%): max +0

Core clock (MHz): max 975

Memory Clock (MHz):max 1400

Fan speed(%):auto max 25

I'd run it at stock for awhile first to see what kind of temps you're dealing with. As I recall, it will boost according to temps, so lower temps = higher performance boost. You may want to re-tim it depending on what the temps are like.
