I just bough this and its due to arrive on wednesday and when it does I'd like to push a bit further if possible. So, if you own this and tried OC'ing it what did you manage to squeeze out? I got decent airflow inside my case (Intake: Front and Side 120mm fans / Exhaust: 140mm Top fan and bottom mounted PSU).
