I have a buddy who wants me to build him a computer very soon. Right now plans are the Asus P4PE, but that MSI SiS 655 looks really really nice and I may have to convince him to wait a few weeks. If they can bring in a DCDDR P4 board for ~$150, I think they a lot.
Edit: that's odd, the Anandtech article had both SiS 655 boards OCing to about 163 FSB. There's probably a difference in how they went about the test, maybe Anand was using an unlocked P4 or more voltage?
Edit #2: The ocworkbench.com article says they took a 1.8A (100 bus) to 143 bus. At that point I'd assume the chip became a factor, no? Anand used a 133 bus and took it to 163 or so, which shows that both websites were able to overclock nicely, if not the best. Still, neither article shows enough about their OC testing procedure to draw an accurate conclusion.
