Seriously though, if your going to do anything that's going to heavily utilize the CPU, get a desktop. Much faster performance, and most likely cheaper =/
At stock speeds, the SB mobile and SB desktop aren't that far apart in benchmarks and real world usage. Obviously SB desktop will absolutely destroy the mobile CPUs once overclocked, but they aren't as far apart as you think.
That review details how SB mobile stacks up to Bloomfield and whatever quad-core Arrandale was called.
That review looks at the differences between the i7-2820QM and desktop SB at stock clocks. Because of hyperthreading, the i7-2820QM pulls ahead of the i5-2500k in some benchmarks.

I don't agree. Mobile SB quad-cores have integrated graphics so as long as the manufacturer enables that feature you can have a quad-core in that will sip power very well. Speedstep is remarkably good at keeping power consumption down when using only an integrated GPU and the CPU on battery. My W520 with an i7-2720QM can get more than seven hours of battery life on a 9-cell while using the IGP.Edited by e30kid - 6/22/11 at 11:13pm
