X220t Outlet screen and processor models

[enthdegree]

Hello, everyone. I just posted a similar post over at the notebook review forums but just found these and thought it may be more suitable to post here too:

I'm about to buy an X220t from the outlet store, the only thing that's holding me back are these two things:

In the outlet descriptions of a few X220ts, I notice the screen is either listed as a '12.5” HD WXGA (1366 X 768) IPS, MultiTouch LED' OR a '12.5” HD WXGA (1366 X 768) IPS' (No 'MultiTouch') I was wondering if the one without multitouch meant that it is the Gorilla Glass outdoor viewable display.

The second thing is the processor. Many of the X220ts in the outlet store contain i7 2620M CPUs instead of 2640Ms as are being sold in the regular store. Are these significantly different processors? Are they comparable in performance?

It'd be great if someone could clear this up for me, thanks a million!!!
