Help with new computer

I plan on building a spare computer...  I found a decent motherboard(a FIC AZ-11,) but I can't decide what videocard to install.  I have a 3DForce B-16 AGP 4x (nVidia RIVA TNT2 w/ 16M RAM) and a Voodoo3 3000 PCI w/ 16M RAM. I don't plan on usinging this computer for 3D programs, but for some emulations and regular internet and office apps.  I have also thought about adding my capture card to it, but I still don't need 3D acceleration.

And don't say buy another videocard...I'm trying to keep this as cheap as I can...my current prices should be less than $50...
