EVGA 670 GTX 2Gb low usage.

Hi guys, so for some reason, in games such as BF3, Saints Row the Third and especially in Borderlands 2, I am noticing some performance issues.

Although in most games I can maintain above 50+ FPS, this card should be able to run almost all games at 60+ with all settings at max, and I am not seeing that.

So I turned on MSI Afterburner and low and behold my GPU is only getting up to 60% usage and I have no idea what is causing it.

My processor is an i5 3450 3.1ghz and I am in the process of Ocing it to 3.5ghz.

Is my processor bottlenecking my GPU or could it be my motherboard? (Asrock B75m?)
