I can tell you from personal experience that DDR with dual Pentium IIIs is not worth it. I have used two boards(MSI Pro266TD & Iwill DVD266u-RN) with that Via chipset, and both produced lower scores with high-quality DDRAM than an Intel chipset with SDRAM. My Sandra memory scores were in the low 900s with the VIA chipset boards and PC2700 DDR running at 166MHZ and CL2, and Intel 815 boards score about 1100-1200 with SDRAM at 166MHz and CL3. They were close, but still lower. I guess that the scores were pretty high for a VIA chipset, but it still isn't worth the extra price of DDR.
