Does the SSD Tip the Scale

The older one will run circles around the newer one as it has a true HyperThreaded (HT) quad core (vs HT dual core) and a stronger GPU both of which are better for gaming and computation workloads.

The SSD of the new one only loads the programs quicker but you can replace the 1tb drive with a 256gb ssd for under $100 if you really wanted to.

Plus the older one comes with 6 free games :)
 
It will depend on what you want to do. The one with the 940m is good for normal purposes with some gpu power but the other is much more powerful.
