Intel is probably a bit disappointed with the overwhelming success of the 865 chipset... despite it being their own chipset, they would obviously want more buyers interested in the more expensive 875 chipset. But alas, things are getting so bleedin' fast that good enough truly is good enough (just hopefully not at the cost of quality). Thus, SIS wants to try and direct some of that budget-enthusiasm towards their new 648FX chipset. Let's see if it is worth your attention.
