Asus to buy XFX, sources suggest
 

THERE is some noise that Asus has acquired very successful XFX. XFX is one of the key Nvidia partners, small but very noisy, which is famous for its success in super high end market. The XFX company is owned by Pine, a far east graphic player.

WE MANAGED to get an official statement from a senior vice president of XFX, Marnie Sutton and we learned that XFX hasn't been sold and doesn't want to be.
