Compatible GPU for A7N66

hello everbody,

I want to buy a graphics for my PC... and its been a while i am wondering which one to...here's my configuration...

AMD Athlon 1800+ XP OverClocked with 133Hz FSB
ASUS - A7N66 MoBo
OnBoard MCP - nVidia-GEForce2 Integrated GPU 32MB
512MB DDR RAM
80 GB Samsung HardDrive

ANd here's wht i want from the graphics card....
- Compatible with my MOBo.
- Guess it has to be AGP as mobo doesnt have PCI-Ex slots
- Should support shaders 2.0 or above as i will be working on lotsa 3D stuff.
- A bit under the budget... say $80 - $100


so can anyone of u ppl suggest any good cards or redirect me to any such thread which suggests some good cards for my config....

thanks in advance....
