MX-2? So what's so new that it's going to be so much more improved? It's 99.9% Pure Silver.... What else can you change? SERIOUSLY!!! What did they like find some new magic thermally conductive material and shoved it in the remaining 1% in between the zinc oxide, aluminum oxide and boron nitride particles?
Silly.
Unless of course they are using 99.9% Pure Gold... Then it might get slightly expensive.
