That is a very nice config. The 1660v2 is high on my list of CPU's I would want to upgrade to, due to the strong single core performance / high clock speed. That said, I was expecting a higher CPU score - 14046 for the 1660v2 is not really that much of a significant increase from my 1650v1 score of 12427 (c.a. +12%).
I am wondering what the improvement would be when stepping up to the 2687W v2 in the Z420. The only real concerns are the 150W TDP and obviously price at this moment in time.
