Help, which rig?

I've finally been able to sit down and put "thought to paper" and have come up with two sweet systems in my price range, $1500.

The only thing is what processor do I want. Pentium 4 or AMD 64?

This machine will be used primarily for Maya 6 (and some gaming )

Here are the specs..

AMD Athlon 64 rig.

AMD64 3000 S939 RETAIL 512K 400fsb S939
ASUS A8V-DX RETAIL mobo
OCZ 2X512 PREMIER KIT [1G] RAM
WD 200G SATA OEM Hard Drive
SP X800 PRO VIVO 256 AGP8X OEM VIDEO!!!
ENERMAX CS-800TA BLACK CASE
ENERMAX 465 WHISPER Power Supply RETAIL

INTEL Pentium 4 rig.

PIV 530J 3.0E w/HT 1MB CACHE LGA775 RETAIL (box)
ASUS P5GD1 915P LGA775 1xPCI-E RETAIL mobo
OCZ 2X512 PREMIER KIT [1G] RAM
WD 200G SATA OEM Hard Drive

What do you guys have/prefer??
AMD has got 64bit and instruction sets that are known to be fast but Intel has got hyper threading with 1mb cache and 800fsb.
