When testing the SiS 645DX chipset I was amazed at the results it was delivering, but when I setup the P4X333 board only to find it was faster I was simply blown away. Though the performance margin was minimal I still couldn’t believe that VIA still managed to squeeze a few extra frames out of a game that was already well over 200fps. The memory performance was also strong on the P4X333 as it destroyed my i850 board running PC800 (on a 400MHz FSB P4).
