THE main reason to go with the P4 would be the 400MHz fsb + DDR memory. Provided you also get a mobo that supports 400MHz fsb and DDR memory. Then the X4 AGP cards will startle you and force you to get that 21" monitor (another $400 to 600 [viewsonic GS815.])
The P3 are basic 100fsb and SDRAM systems.
Intel really does NOT want to have their investment with RDRAM to be choked off with mobo memory supporting DDRAM, so geting mobo support for the Intel cpu and then pairing that to the mobo chipset (ie. VIA) is going to take some research.
Another consideration with the modern mobo is their support for the ATA 133 hard drives (hd), like SCSI performance w/o the $300-600 hd + controller card. ATA 100 hd are not so bad, esp since 30-60GB are near $125, but a full 60GB hd sure takes a long time to defrag!!!
Further having two or three hd, a CD (kenwood) and CDRW (plexwriter), a flopy, couple case fans, gpu & cpu fans means that stock 230W power supply(ps) is kinda antique... so consider the +400W ps, another $100.
Rumor is, having rounded cables within case, instead of the flat ribbon cables will improve internal case air flow, and the rounded cables come in a couple diferent colours; about $4-8 each.
