Well, we are probably comparing apples/oranges when it comes to hardware.
Check my signature, I have the benchmark from SF11. how does it compare with your machine? Also, I only use 4 threads.
My apologies and I certainly can see why you responded the way you did. I should have not quoted your post. I was really just letting the world know BD-X1-r3 will soon be released.
Here my 4 threaded run - not that it means anything since the hardware is not compatible.
