Série grafických karet Lightning společnosti MSI, předního světového výrobce základních desek a grafických karet, si získala skvělé renomé jak mezi pokročilými uživateli, tak ve světových médiích. Nejnovější člen této rodiny, MSI N480GTX Lightning, je šitý na míru pro extrémní přetaktování. MSI představuje unikátní architekturu Power4, která modelu N480GTX Lightning poskytuje nejsilnější a nejstabilnější výkon a výrazně zvyšuje potenciál pro přetaktování. Svědky jedinečných schopností karty byli účastníci a návštěvníci finále MSI MOA2010 v Taipei, kde švédský mistr v přetaktování “elmor” překonal dosavadní světový rekord v 3DMark Vantage. Grafická karta MSI N480GTX Lightning je doslova napěchována exkluzivními funkcemi, včetně nového systému chlazení Twin Frozr III, který je v porovnání s referenčním chladičem schopen uchladit grafické jádro na teplotu o 18 °C nižší. Samozřejmostí je také funkce trojnásobné změny napětí (Triple Overvoltage) pomocí unikátního nástroje pro přetaktování MSI Afterburner.
