Rough idea on specs?

[Avimimus]

There will be a resource creep with subsequent addons - so it is actually ideal to buy one or one and a half years after release.

Priorities should go to RAM and CPU. The GPU really is an afterthought for flight simulators. Track-IR or a good joystick would be higher priority than an advanced card.

Advanced rendering options are optimised for close range high detail rendering of small numbers of object used in first-person-shooters and not very applicable to the needs of flight-sims.
