Anything with the Nvidia 6600GT chipset on it. I have one in the Gigabyte
and XFX brands and they work outstanding. The XFX is in an AMD 3000+ AGP 8x
and the Gigabyte is in an Intel 3.06 AGP 4x.
With the Gigabyte, their software has the ability to change the speed of the
memory and bus. The XFX leaves it to the Nvidia Driver properties to do
this. Either way is acceptable.
