"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You yourself listed them in order of best to worst out of the bunch...

1) i7-3940XM (best)
2) i7-3840QM
3) i7-3740QM
4) i7-3540M (worst out of this bunch)

Although 1 and 2 are fairly close and for the money difference you might want to go with 2.  It also uses less power which is good for a Laptop.

Here is a comparison between them.
