Well..
A 2.8 will NOT get the job done......
A 3.2 is in that neighborhood that FSX wants..
True...FSX requires a clockspeed ~3.5GHZ.....although bear in mind that the OP is running an AMD 2.8ghz dual core chip which is nowhere near as powerful as an equivilant Intel processor. AMD have upped the ante with their latest Phenom II processors, but their previous have lagged behind the intel dual and quad core chips by a huge margin.
As a (poor) example...I had an AMD dual core FX-60 (2.8ghz) chip in a previous system and it was easily outperformed by an Intel Q6600 (2.4ghz) rig.
