I think the reason that you have had no answer is because you don't state what graphics chipset you have.
It was quite hard trying to figure what the graphics are capable of as well.
I believe the 5735 has the Mobile Intel® GM45 graphics setup.Since this has pixel shader 4 and is direct x 10 compatable it should have no trouble running Flight sim x which will run on a 32mb direct x 9 card.
Your Graphics memory is 64 MB of dedicated video memory, up to 1695 MB of shared system memory.
Your ram and CPU will easily handle it,so it all looks good to me.
I would say go for it.
