What graphics card is actually needed?
I read the Ubuntu Wiki article about Steam on Linux and came out more confused than I was coming in. I went on the #ubuntu-steam channel on freenode and was met with a channel with no ops around and nobody actually talking about anything. So I come to you, Steam Discussion Forums, to ask my question.
The wiki article says a minimum of an "nVidia series 6 or AMD series 5" card. That... has absolutely no meaning to me. There are two nVidia card series with a "6" at the front of them, and at least 3 if not more AMD/ATi card series that could be considered "5".
On the ATi/AMD side, we have the RV520 chip (used in the X1300-X1950) which wouldn't actually be known as the "series 5" to anyone other than a developer, the X800-X900 which were actually the 5th radeon cards released in total, and the HD5000 which would seem a rather high requirement.
On the nVidia side, we have the GeForce 6xxx series and the GeForce GT/GTX 6xx series. The former doesn't work for the contents of the article because it suggests installing the experimental 310.xx drivers, which don't work on the GeForce 6xxx (or 7xxx for that matter), and the latter doesn't work because that would be an astronomically high minimum requirement for just running steam.
So, yeah. What? What exactly is meant there? What are the *actual* minimum requirements, in terms of actual graphics card models?
