|I'm running a 512MB x1950Pro AGP on a PIII system myself. Works just great, even overclocked! AVOID the Radeon HD 2000/3000/4000 agp cards--they're nothing but trouble. |
If you can't find an x1950 Pro for less than $80, just search for older NVidia cards on eBay. All nVidia AGP cards work great on older boards--for a while I had a GeForce 7950GT AGP running flawlessly on the old PIII board. You should be able to find lots of cheap 7600GS/GT boards on eBay.
"i will upgrade this one to vista x32 bits"
Unless you have a Vista DVD waiting to be installed, get Windows 7 instead. Sure, its official system requirements are slightly higher than Vista's, but that's just Microsoft being careful. In reality Win7 runs faster than Vista on old school systems. Sometimes much faster.
