HI - we use a lab full of Compaq Deskpro 4000 5200MX - all with crapster modified S3 cards, they need the Xfree 3 driver XF86_S3V and they work OK, but there is some lag and distortion, especially when scrolling documents. Will replacing these 1MB wonders with nice 32MB PCI Nvidia GE Force cards increase performance of the terminals?
