disagree. tualatin celeron eats the duron, especially done right. clearly it comes out ahead in most tests, and that's without even mentioning the fact a tualatin celeron 1000a is the easiest overclock ever at 1330. also, the sis635 chipset could in fact marry this chip to DDR, which wasn't tested here.
even without all that it still comes out ahead in many "every day" tests, and to just look at the wattage difference, the very slight extra duron oomph simply doesn't justify the fan noise. this line of celerons were the best deal in town when they came out. they are the cherries on top of the 686 cake.
