Jimmy - what situation maxes out memory bandwidth? Highest texture quality + quality AA filtering? I'm not sure if this maximizes the need for bandwidth. I know it loads up a greater amount of video memory potentially maximizing capacity, but how do you go about maxing out bandwidth? Is there a special test?

So you DO think it has a memory bottleneck? IMO it could definitely use faster memory. IDC @ anandtech says, "f you can overclock the GPU cores and see a performance improvement that exceeds that which comes from increasing the memory clocks then that is about as close to proof you are going to get that your compute system is not memory bandwidth constrained.
