MSI Showcases R9 280X Gaming 3G LE Graphics Card with Under-Frequency

MSI Gaming lineup of graphics cards is currently rich in numerous models targeting gamers with any taste and budget. Nonetheless, the company never stops pleasing its fans, so the appearance of a new R9 280X Gaming 3G LE (Light Edition) card is quite viable.
