Yep. You read it right. PCI !!
The situation is this:
I need to buy a used/new PCI video card, that will give me smooth 3D
and allow things like MLB streamed over Boxee play well.

Although I dual-boot to Windows for games, that's all I ever use it for, or care to even be on it.
Because I have an ATI x800xt AIW, the open source drivers lack for me for the Boxee situation on Linux.

Hoped to just pick up an old PCI card for Ubuntu use only.
I can select AGP/PCI in my Bios, so that's good, as I'll have both installed at the same time.

But it's been a long time ago.
What's a good card for me that is still working good in 10.04?
