Introduction
NS80-EA (SIS 648) sometimes I wish they would have shorter names on the motherboards But the name really doesn’t matter since this board is supposed to rock!! Does it?? Well it�’s up to you to read this article and decide This motherboard is equipped with the SIS 648 chipset. I compared my Amd Xp 1900+ with KT400 and a P4 with this motherboard had really REALLY interesting resuslts I must say.
