What about this system for FSX:
Intel i7 950 @ 4.6 GHz Windows 7, Forcware 182.52, ASUS P6T7 WS, GTX-280, Memory: OCZ Blade 2000MHz 7-8-7-20, 2x SAS 15k Raid 1 with 256MB Controller.
I got all this info from a friend. Still have to get more. Cost is not a factor since I'm getting this for about 500$ - 1000$.
