Take a look at this sim package including:
AMD 3.4GHz Quad-Core Processor
4GB RAM
160GB, 7200-RPM Hard Drive
ATI Radeon HD 4250 Video
27-inch LCD (1920 x 1080 pixels)
Windows 7 Home Premium
Lockheed Prepar3D Flight Sim (the next generation of Microsoft Flight Simulator X)
$2,490.00 (rudder pedals not included) plus applicable tax and freight. At this price I assume all necessary tweaking has been done!
