There are no dual Althon mobo's that I am aware of, however AMD and VIA are releaseing chipsets for duals in the next month or so. The reason Win 98/95 is not used is because it doesn't support SMP, and if you are running a high end proggy you need the extra CPU power. The main use of the vieo card is for real time viewing, some programs offload certain functions to the GPU, but the CPU does most of the heavy lifting. RDRAM is an expensive joke, very small performance gain for a huge price premium, you can expect a 7% speed increase with about a 25% price increase in system cost. And that 7% is under the best conditions.
