Need to Upgrade ABIT KG7 & AMD 2100+ Any Words of Wisd

I'd kind of like to throw myself on the mercy of the court here and just ask this question st8-up.
It's time to upgrade my MO & CPU. Below is the gist of what I currently have. I Run things like SQL Server, Personal Oracle and do a lot of Video Rendering.....
Anyone who is sort of on top of today's MO's & CPU's who would take a moment to advise me where I could spend a few dollars to get the most bang for the bucks--greatly appreciated.

Things that Gotta go
MO ABIT KG7-Lite
CPU AMD Athlon XP 2100+

Things that prolly should go
Video Card ATI Radeon 8500 (LE) 64 Meg
Xircomm Hub for 4 extra USB devices (That gives me 4--and I need em all)
Ethernet SMC Easy SMC 1255X --would expect this to be built into new MO

Things I might like to keep
Memory 2--512 Corsair CMX512-2700C2 DDR-SDRAM 166 MHz (PC2700)
Sound Card Creative Labs Audigy 2 Platinum with extended interface & 1934 Firewire*
Firewire PYRO Platinum DV IEEE Firewire*
Hauppauge Digital Video Recorder
Hardisks 1.7 Terabytes of mostly Maxtor--
currently using a Maxtor K14PCAT133 IDE Controller for 4 extra drive slots.
DVD Burners Pioneer DVR-108 & Pioneer DVR-104
Monitor Samsung SyncMaster Monitor
TabletWacom Intuit2
I still require a parallel port and have a IDE card
& I stil require 2 regular serial ports--I have one on an IDE card

*Built in Firewire & Ethernet would be a nice to have.
Hhhhmm,
I haven't been here in so long that I totally spaced out that I have a sig below!!!
