Cards made using ASUS Auto-Extreme technology promise to have better quality and greater overclocking stability. ASUS also explains that these cards will no longer have pins and prongs on the back of the PCB since the board components are soldered into pads on the board itself rather than placed through holes on the PCB:
ASUS graphics cards are now produced via exclusive Auto-Extreme technology, an industry-first 100% automated process, and feature aerospace-grade Super Alloy Power II components for unsurpassed quality and reliability.
ASUS Auto-Extreme Technology also allows ASUS to create circuit boards that are completely smooth as everything is surface mounted for the very first time thanks to Surface Mounted Technology (SMT). This means no more pins and prongs will be poking you on the back of the board when you are installing your video card in your gaming PC since board components are soldered onto pads on the board itself rather than placed through holes on the PCB. ASUS believes this moves them a step closer to producing the best graphics card possible.
