Now this will come to something just over 1000 Euro. But it assumes you start from nothing and most people will have monitors, cases, Windows versions they can use. So for most users it will costs something like 700 to 800 Euro's. For this you get a box that will run FSX great, with framerates over 20 fps in even the most demanding locations. For FS2004 it will be overkill but as there is almost no progress in single core CPU speed you will waste at least half the CPU no matter what you do.
