AnandTech has updated their popular high-end buyers guide and split it up into two parts: basic high-end and ultra high-end. You can take the latter suggestion as “a good way to spend money without seeing immediate benefits.”
As far as the platforms themselves go, little has changed in the past seven months in terms of overall architecture specifications. Intel continues with the venerable Socket 775 platform, while AMD’s relatively new AM2 promises to be used for some time to come. The NVIDIA 680i and Intel 975X chipsets own the performance arena for the Intel Core 2 processors, while the NVIDIA 590 chipset leads the AMD Athlon race.
Although Intel has been cleanin’ up the place, they did not exclude AMD which was nice to see. Also nice to see is the fact that either system offers four cores for essentially the same price.
