Sorry to butt in, but I noticed that you have an Lenovo laptop. I am getting one, but I don't know what I need in order to run M8 on it. I will be using going version of windows on it.
I had to get another desktop 3 years ago, an Lenovo just to run version 7. My IBM desktop could not handle M7.
Thanks

Interesting. I decided to play with this too (on a Lenovo notebook with two cores, running a 32bit linux). If I choose to have Mathematica fire up another kernel "as needed", things run fine. However, if I ask it to start two kernels "on startup", the Benchmark runs for a long time (I haven't let it complete yet) and pegs both cores at around 100%. It also prints no output. Perhaps a bug?
