Its old, inaccurate, been disputed and proven wrong countless times. VIA P4X266 is the worst P4 Chipset available. SiS looks pretty good, but I'll still take an 845D over it.
<< In reality, if you have PC2100 RAM and no desire to overclock, the i845 chipset is a better choice, but the fact is that with other chipsets utilizing PC2700 RAM (which is a bit expensive right now) and the ability to crank up the front side bus, the Intel chipsets fall short. >>
Huh? What chipset you think most people are using to overclock their P4's via FSB with? Yes, the 845D. Good PC2100 such as Crucial will do PC2700+ just fine.
