Well, for our first SiS 735 board we have to say it rocks. Despite the lack of overclocking on the motherboard, the results blew the roof off the AMD 760 and the KT266. As for the board itself, it is an extremly stable, well designed OEM motherboard and offers very little to complain about (only the overclocking but let us specify its OEM not OC).
The SiS Chipset alone gets a 9 out of 10 rating, but overall:
Rating - 8/10
