Unlike motherboards, where manufacturers have options to add features and components to differentiate one board from another, graphics cards often are manufactured with the same design specifications. In order to stand out in the sea of vendors, manufacturers often resort to after-market coolers to provide better cooling. In addition, they will sell cards with higher clock-speeds than the reference speeds, or bundle it with different accessories and games. They may also provide different warranty options, such as lifetime warranty or a double lifetime warranty.

Thus, choosing a GeForce GTX 260 card from manufacturer A that sells at $30~$40 more than the same card from manufacturer B often means that you are getting more bundled gear or a longer warranty, but the physical hardware from both companies are virtually identical. To stand out, a company needs to be inventive and willing to take some initiatives. This is where Gigabyte comes in with their latest line of graphics cards.
