Building a new PC... here are the specs

[Snaglepuss]

I am building a new PC for 3d apps. I will be using ZBrush and Maya 2008.
I want a nice system, so I would appreciate the advice of fellow ZBrushers
Here is the first draft of my parts list :

-Asus /p35/FSB1333/Crossfire/GBE
-Intel Processor, Core2 Quad Q6600, 2.4GHz 8MB L2 Cache
-Kingston PC5300, DDR2-667, 1024mb (4 sticks)
-Seagate Hard Drive, 80gb, SATA-2, 8mb Cache, 7200rpm, 3.5in
-Seagate Hard Drive, 500gb, SATA-2, 16mb Cache, 7200rpm, 3.5in
-LiteOn DVD Dual Layer DVD/CD Writer Drive, Black, 2MB cache, DVD+-R 16x, DVD-DL 4x, DVD+RW 8x, DVD-RW 6x, CDR 48x, CDRW 24x, CD 48x (2 of them)
-Video Adapter, XFX GeForce 8800GT 512MB
-Windows XP pro

This is the first one I have built exclusively for 3d modeling... Any suggestions would be appreciated
