Now's a good time to build an intel P4 Northwood system, but not an AMD Athlon XP system. It would've been, with the introduction of the Athlon XP 2200+ Thoroughbred and KT400, but the former is so far a disappointment and the latter isn't out yet. Graphics side wise, the introduction of the Parhelia should've been a great time to upgrade too, but again it has been a disappointment performance wise so far. So, if you want an Athlon system, wait for the Barton, otherwise, go for an intel P4 Northwood system, PC1066 and a GF4 Ti.
