I have a pretty recent (fall 2008) developer PC that I put together myself. I was generous with most of the hardware but bought the cheapest NVidia card with Linux support because I don't need much in terms of graphic (no gaming, no video etc.).
Now I want a model that still doesn't have to be high-end but should support two monitors. Linux support is a must. Now that's still plenty to choose from. Can anybody recommend a particular model? I'm slightly leaning towards NVidia because I was under the impression that their cards work well on Linux.
Of course, buying another cheap single-head card is also a valid option (I have plenty of free slots). Are there any pros / cons on that one?
