Possible Save for P4 System with AGP interface

[bcgone]

Uber Techs,

Would anyone care to help me salvage my aging gaming rig. Here is my current status:

Intel P4-2.8Ghz (old Prescott core, socket 775, 1Mb cache)
Asus P5P800
Seagate Barracuda 7200rpm ... 160 GB
2GB DDR400

My video card just croaked (Radeon X850 Pro 256 Mb). The machine was handling DDO just fine, I was not experiencing lag (more than the avg Joe) and transitions seemed to be about as fast as any group members I've gamed with. Any saving suggestions or should I relinquish this to my daughters Hanna Montana game???

I appreciate any suggestions on card replacement or other tweaks to keep this running.

BC
