Hmm. This thread (here and Moo-wards) seems to be using MHz as a performance metric. It's well-known that Via chips previous to the.. C5X, is it? I was never much into Bible study 
.. had a half-clocked FPU; so far as I know, the 750CX and friends are not so limited. It's not easy to find SPECmark numbers for the Via chips; anyone have any?
From what I've seen, the VIA C3 sucks fataly. A C3@1 GHz is comparable (remember, from the tests I've seen) to a Pentium II 400 MHz / K6-III 450 MHz.
To sum it all up, it sucks :-P
