ATI Radeon X800XL (R400)

While the R400 series is just an extension of the R300 class these faster GPUs offer a much more pleasing experience with desktop eye candy. Using an ATI Radeon X800XL 256MB (resolution at 1680x1050), which is one of the fastest graphics cards right now with open-source X.Org drivers, it had performed extremely well. The desktop while idling and during basic desktop usage was always over 200 FPS and the lowest that the frame-rate had ever dropped during heavy usage was to about 25 FPS. Other system components had included dual Intel Xeon Clovertown quad-core processors and 4GB of RAM with Ubuntu 7.04 Feisty Fawn.
