So after two days it is done, the basic FSX install is on the new machine, including all payware (several Aerosoft AIrport and -fields in Germany, REX OD, UTX, GEX, Traffic X and my hangar of payware a/c). Some freeware still to come, but OTOH great to get rid of scrap.
The new system is a Asus P2P67 with a i7 2600k, 8 Gigs of RAM, a Asus GTX 570, a 64 GB SSD for the OS (Win7 pro), a 1TB Samsung HD as storage and a Audigy Gamer.
Holy #%&*$#, this thing is FAST. When I unlock the fps limiter it shows over 100 fps at times over rural area in the default Cessna. And this is even with stock CPU speed of 3.4 GHz, I think with the Thermalright Archon Cooler, there is the possibility of adding around 1 Ghz more speed. I locked it at 40 fps though.
Great fun!
