Charlie at The Inquirer has posted his predictions for the CPU market in 2006. An interesting read if you're considering an upgrade this coming year.

In late Q1 or early Q2, we will see AMD update its line to the 90nm F-Step (FS) cores. These will bring two major things to the desktop, DDR2 and lower power consumption. It does add a lot more besides, a new socket, faster HT, improved cores, and other more server oriented features, but the two listed are the most important for the desktop. We'll leave server parts for a different day.
