Max possible for DDR3 1333 eight channel is ~85GB/s so this is ~48% efficiency atm, in comparison to ~80% on the quad socket istanbul system with DDR2 800 (theor. max ~51GB/s).
Particle here has an dual istanbul setup, maybe he can run a few benchmarks for comparison. Maybe stream at the same cpu and nb clock speed.
