just bought my new r9 280x today , and god was it a huge upgrade from a HD 6870 , now to the topic, i have the card on stock speeds for now , the card runs super cool and my case has good airflow so temps are no biggie , can someone help me out in overclocking this card , also im using CCC (amd overdrive) to overclock as MSI Afterburner never saves my OC settings everytime i boot up windows ? thanks
