OC is short for Overclock- Going into BIOS and upping the speed of various components, mostly CPU speed, FSB, video card, and sometimes RAM. Look in the FAQ for more information.
Since it requires (aside from knowledge) more heat dissipation, extra voltage and all that good stuff, you need to take it into consideration if you might be OC'ing your comp in the future.
I argue with people on internet message boards.
