That type of a mobo would out perform the Intel igp @ 733mhz most likely.
You're probably right but I compare Intel IGP with HD 4200 without SidePort because it is more correct like this.

Indeed, IGP's are very dependent about memory bandwidth. If I set the memory to 1600MHz (from 1333MHz default) I get a very nice gain in games !
