Heh.  Not with Intel's screwups as of lately.  They generally are only
having problems with the 1GHz+ processors right now, though.

I've _never_ had good things to say about VIA, ALI, or SiS chipsets.  
How many ways can a company break a f@#*ing chip?  Can _anybody_ make
a decent chipset these days?  Even Intel has managed to screw things
up royally in several cases.

The i815 will probably work much better than the VIA/SiS/ALI
solutions.  It is rather pitiful, however, that the ancient 440BX is
still the most reliable (and fastest in many cases) chipset that Intel
has.  You might want to consider the ASUS CUBX or another BX-based
board that has a "supported" 133MHz FSB along with some of the more
modern amenities (ATA66/100, etc.).  The only problem you run will run
into with one of those boards is you will need an AGP card that can
handle an overclocked AGP bus.
