VIA/Cyrix has always trailed in performance in FPU and MMX operations, and the C3 is no exception. VIA's positioning the processor as a cool, low-power device for mainly office productivity and web surfing, not for hard core 3D gamers. I'm interested in it for the possibilities of a silent computer with no fan on the heatsink (does anyone know which of the various speeds can use just a passive heatsink?). It's too bad that the C3 and heatsinks for it are so hard to find in the US.
