Definitely diminishing returns on the memory, if all you do is pump the memory the gains are negligible. But core & mem incremental increases seem to have a real benefit. I ran each benchmark twice (each is 3 loops long) and results never different more than a 0.2 fps (which makes the final result even more meaningless).

I was gonna simply have the image display but it was too damn big. Link instead.

Summary:

Crysis VH @ 1080p

850 core /1200 memory 37.2fps

890 core /1220 memory 38.34fps

900 core / 1230 memory 39.06fps

900 core / 1300 memory 39.33fps
