right, ATi as well make their own cards (started poor, ended poor)
nVidia have research facility only. so AIB partners make their products on their chips.
Asus, MSI, Leadtek (Winfast) are my used manufacturers in nVidia cards. trusted and gauranteed.
else many makes nice, Asylum (had read a review, looked nice, but am not gauranting), else creative (not self tested)
