i am upgrading my system to a P4 CPU and would like a mobo/chipset that has excellent OCing features, great stability, and great bandwidth. at first i only wanted the P4 mobo/RAM combination that provided the most bandwidth, money being no object. but after doing some research, i found that i could get performance and bandwidth very close to that of the i850E/RDRAM combo, leaving stability, overclockability, and reliability up to the mobo manufacturer. and so i am torn between the i850E and the SiS648 (which isn't on the market yet, but Shuttle will be putting out the first board to use this chipset soon). although money wasn't an object in the beginning, i thought why not make it an object, seeing as how it isn't worth the extra $200+ to get an i850E board and RDRAM for a minimal performance and bandwidth gain. i am very much leaning toward the SiS648, but i want as many opinions as i can get on the topic.
here's what want to know so far:
1) when will the first SiS648 mobo (the Shuttle AS45 v1.2) be available for purchase?
2) why does the SiS website say it supports only DDR333, while everyone else says it supports DDR400 (and Tom's Hardware Guide's review on the SiS648 reference board proved that it does support DDR400)?
3) what range of fsb frequencies can i select from in the BIOS, and if nobody knows off the top of their head, where can i find that out?
4) do features like IEEE1394, serial ATA, Ultra DMA133 come on all SiS648 boards b/c they are integrated into the chipset, or does the mobo manufacturer decide whether or not to include those features? (the reason i ask is b/c if ASUS put out a mobo w/ the SiS648 chipset and had as many great features that the Shuttle AS45 v1.2 does, i would get the ASUS over the Shuttle b/c i know that ASUS makes the most stable and reliable mobos.)
