i encode and process video in HD for about 6-8 hrs a day, surely i would take on the multi threaded CPU. oh and trust me i know that stuff, since i am using 2960xm at 4.1ghz on all 8 threads at the moment and i only wish it could go faster. (reason i dont run it on 4.5ghz like how i posted b4?, cause im a pussy and dont wanna risk my CPU, and i suck at overclocking)
this also includes 3D and CAD rendering for my university work as well, and brag rights.
speaking of which, 3940xm is out on notebookcheck.pl release date is said to be OCT 1st.. kind of late, could probably just wait for Sandy E, or IVY E, or haswell mobile extreme cpu..
