If you are trying to do anything with FSX on this laptop you will need to spend close to 1500-2000
the video cards and processors are not made to run software like that and they make sure they get the money for the ones that do

so forget FSX on anything less than that. You need at least a 8800M GT/GS or 9800M GT/GS video card in a laptop for FSX
The 9600 cards are barely FS9 able but they will run it
So that aside, if this is just for school and work its all about what your installed programs need for memory (amount) as some engineering programs run much better on 4GB+ which means a 64bit OS should be installed. And, what you need for support in CD/DVD/floppy drives
just about anything will do as long as it mees your needs for school or work
