I'm in the process of moving, so i'm using a dinossaur as my main rig, a Pentium 4 2ghz with dual monitor. Geforce 3ti500 as the main card, and a voodoobanshee from 1998 for the second monitor. The system uses 640 mb sdram (not even ddr).
This is how the system did on both cards:
Geforce 3 ti500 64 mb from 2001
Voodoo banshee pci 16mb from 1998
