Duke, I agree with Chipguy, but I think that unlike the 850 and RDRAM, DDR2 and PCI-Express have wide industry support and at some point, they will be ubiquitous technology. Having said that, however, they seem to be ahead of their time. Anand's review shows that even a native PCIe interface offers no benefit right now above AGP 8x, and the 800MT/s FSB of the Pentium 4 will not allow the bandwidth of dual channel DDR2-533 to benefit, either. What we do know is that the DRAM manufacturers will have much better yields on DDR2-533 than any kind of overclocked DDR533, so when 1066MT/s FSB becomes available, users will see a benefit to moving to DDR2. Until then, I agree that the 915/925X are much ado about nothing. The exception might be for those people looking for integrated graphics and sound. In that case, THG shows that Intel has come a long way in getting their graphics performance competitive. A few driver issues aside, it looks like newer games will be playable on the integrated graphics, and I think that will be a competitive advantage for the mainstream market.
Finally, a sore spot of great concern is the power dissipation. If these graphs are correct, then the new socket 775 is hotter and higher power than anything else before it. This is an area where much cost will be sunk into thermal solutions, and it's a great opportunity for AMD to seize a competitive advantage.
