Just picked one up cause it has mounting slots that will let you easily mount on your F1 standards on any intel socket size. My GTZ I had to change the bracket, My XT had too much back pressure, so I tried this one and like it. Core temps with wet ice in the chiller stay in low 20s at 4.5ghz on all 6 cores, significantly better than the GTZ.
Solid copper body makes it great for cooling and for looks. I'd a bought the silver version if Sidewinders had them :(
Anyway, good all around all socket CPU in the higher price brackets.
