In this review we will be looking at MSI version of this new card called the Radeon HD 4890 OC. OC stands for overclocked meaning it comes from the factory with a slightly better clock speed from what ATI had intended. Typically OC cards don't overclock well but with a little tweaking you can usually squeeze out a few more frames or, simply leave the card alone and enjoy the nice performance boost.
