Buying a new graphics card is exciting. To start with, you can overclock or undervolt a graphics card on your own, granting better performance at no extra cost. Simply install the free MSI Afterburner app and you can enter the world of juiced-up graphics cards without wasting extra money. To boost their profit margins, companies may offer OC versions of the same cards at a higher price. Unfortunately, non-OC cards are hard to find, as manufacturers seem to default to OC versions.
