Tucsonan #1 never make judgment of anything by a single article.
#2 statements like these "Just to quickly cover one more time why I hate the Pentium 4 so much" do not make for responsible well-balanced journalism. And although the author makes some valid points, he oftens sounds like a zealot on a Jihad.
#3 After reading the article I found quite a few inconsistancies and errors concerning clock cycles and CPU architecture.
I will not be trading my Dual Pentium III 1000MHz anytime soon for a Pent IV, but it certainly is not because of the article you pointed out.
Also, remember this, it takes a software programer using the instruction set of a cpu properly and optimization to realize the potential of any cpu.
This is why certain applications, being optimized for use on Pent IV's do so well case in point Quake, in this the Pentium IV excels.
But unfortunately because of the architecture used to achieve high bandwith in media applications, in everyday tasks it flounders and that's where the PIV is loosing ground. Also that coupled with the fact that previosly you could only use RDRAM ( RAMBUS) and it was way overpriced. BTW the prices are coming down, Mushkin has 128 MGB sticks of RDRAM for $48, so even though it's not as inexpensive as DDR or SDRAM it's now within reach for the average user.
My advice has already been offered here, buy the dual processor board and use a single processor or go for the gusto and put dual PentIII's in wether you use it or not you'll have plenty of clock cycles to do anything you want and truly multitask. Something NO single processor board will ever truly do.
