Gigabyte GeForce 7600 GS 512MB AGP -> can not do it end of story
I have AGP port, so if I find Geforce 8400 PCI ( yes I do not have PCI-e slots) it is posible.
Or do I need "the G98 chip" on Geforce 8400 ?
This is some list that I found:
Also, what is state with ATi drivers on Linux ?
AFAIK situation is even worse for my need, or I am wrong (is there some ATI AGP card that can do it)?
