I dont have a really powerful operation system so is there any way through which I could decrease the polycount?
I have already removed doubles from my meshes and un subdivided.

This will drastically reduce the poly count of your mesh, but at the same time it won’t be noticeable! As the quality of the model remains almost intact (that is, if you don’t exaggerate with the iterations, of course)!
