Hey guys I have a quick question what is the difference between the MSI GTX 560TI and the MSI GTX 560TI OC addition? Is there anything different beside the over-clock. like is one a custom PCB than the other or can one handle more voltage than the other. I have been searching all over the net and just cant seem to find any difference between the two not to mention not many people have got the stock msi 560TI.
