I found that usually MMOs tend to need much RAM (4GB or more) and a powerfull CPU (~3000 MHz x 4 or more) for smooth gaming.
MWO is not a traditional Big-Scale-MMO so i guess moderate CPU Power will drive it well.
But they also gave interviews that they go for cutting edge technology so maybe its higher.
Physics should scale well with CPU-cores for example.
Best to wait until you can test it - a computer is ordered in a few minutes if needed.
For Laptops the GPU is usually a weak spot too.
PS: I have read the Nvidia 335m does not support Directx 11
