Keep in mind that video RAM isn't a very important variable in getting good 3D performance as long as it's not too low. Video RAM's main function is to store textures, so it presents a major performance bottleneck if you don't have enough, but performance isn't significantly increased if you have a surplus. Clock speed and shaders are '''much more important''' in overall performance.
AFAIK, there isn't any sufficient performance difference between chipset RAM
and shared memory. The only caveat is the fact that when the shared memory
gets used, there is less RAM remaining for other functions.
