XFX Inc. is a Chinese electronics company that specializes in the manufacturing of video cards, power supplies and motherboards. XFX has its headquarters in Ontario, California, and is a division of Hong Kong-based Pine Technology Holdings Limited (). Video cards Originally, XFX produced only Nvidia graphics cards; in 2009, XFX switched to manufacturing ATI (now AMD) graphics cards. While it kept selling Nvidia mid-range cards for some time, it later ceased producing any GeForce graphics cards. Warranty All XFX graphics cards sold in the US or Canada previously came with a "double-lifetime" warranty. This warranty gave lifetime coverage to the original buyer and, in addition, a subsequent owner of the used graphics card. However, it was only valid if the card was registered with XFX directly within 30 days of purchase. In January 2012, with the introduction of its Radeon HD 7970 graphics cards, XFX silently discontinued its famous "double-lifetime" warranties, stating it was not sustainable. The lifetime warranty is not available for Radeon R 300-series or greater. It is only offered for the following models if they are registered within 30 days of purchase: XFX Radeon R 200-Series Double Dissipation Edition and HD 7000 Series Double Dissipation Edition Graphics Cards. XFX Radeon R-Series and HD 7000 Series Graphics Cards with 10-digit model numbers ending in "R" (example: "FX-797A-TDFR") XFX Radeon HD 6000, HD 5000, and HD 4000 Series Graphics Cards XFX GeForce GT 640, GT 630, 520, GT 430, 200, 9000, 8000, 7000, 6000 Series Graphics Cards purchased after April 17, 2007. Overclocked cards In addition to reference clocked graphic units, XFX also supplies overclocked graphic units that are similar to the ones produced by BFG, EVGA and ASUS. This is targeted at the enthusiast market, as well as those who may be unfamiliar with overclocking. These overclocked cards are often sold alongside cards with standard clocks at a slightly higher price. Overclocked systems are commonly designated with the names "Extreme Edition", "XXX Edition", "Black Edition" or "Alpha Dog Edition". Fatal1ty video cards In 2006, XFX made an agreement to use the name of a computer tournament game player, Johnathan "Fatal1ty" Wendel, on a division of graphics cards. However, the Fatal1ty branding has seemingly been dropped for unknown reasons. Radeon cards XFX produces many AMD Radeon cards from the R700 Series to the Evergreen series. From the R700 family, XFX only produced high-end and enthusiast-level graphics cards. From the
