FX5200 can't do 1680x1050, so be warned. Max vertical resolution through the DVI port is 1024, so you can only hit 1280x 4:3 res, or 1440x 16:9 even through custom hacks. The entire 5 series (and some 6 series) cards have issues as they were not built for widescreen or screens larger than 17" using DVI.
Analog works fine till 2048x on these cards, just the DVI has issues.
