I understand your frustration with your old RT2000/2500 card. Matrox has come a long way since then. as has XP and current intel chipsets.
The RT.X2 hardware is very stable and reliable. while the certified system list isn't very big, Matrox has done a very good job testing and evaluating motherboards and graphics cards. What we've found is that as long as you stay close to the recipe, you'll get very good results. So while a specific mobo may no longer be available, using the latest version based on the same chipset will get the job done.
we put together a nice little FAQ on the RTX2
