yes the CPU would be bottlenecking it there.
the CPU plays a part in making the graphics. it makes all the shapes and sends them to the graphics card, which colours them.
each object is made up of polygons. the more polygons, the better the shapes will be. older graphics sometimes looked "boxy" because they didn't have many polygons. newer graphics have millions of polygons and things are a lot more rounded.
of course, the more polygons, the more the CPU has to deal with.
on top of making the shapes, it also processes the physics. for example X object is moving Y fast in Z direction, and has an acceleration of A in B direction etc....
2GB RAM is not essential for games. most will run with descent frames on 1GB, with the exception of maybe FEAR on high settings, and Unreal Tournament 2007
