In our review of the EVGA e- GeForce 7800 GTX KO, one of the most powerful graphics cards available right now, we explained how impressed we were by the performance. The huge overclock, coupled with EVGA’s lifetime warranty, gave it an edge over the other 7800 GTXs that we’ve reviewed, and thus, put it on the top of our list. Today, we will be looking at the XFX GeForce 7800 GTX Overclocked. With a 490MHz core and 1.3GHz memory clock out of the box, it will undoubtedly match the EVGA KO in terms of performance, but we’ll see how it compares in other areas as well. As you may know from our past 7800 GTX reviews, things like price and warranty (along with the usual suspects) are factors for the cards that we ultimately recommend over others.
