Neoseeker published a review of Intel's Pentium D 805

Overclocking the D 805 was an interesting experience.

In some ways, it was the easiest overclock ever. With a big heatsink and fan, the first attempt at overclocking - which was setting the multiplier to 18, and the FSB to 800 MHz at default Vcore - just worked. No muss, no fuss.

A core clock of 3.6 GHz with an 800MHz FSB is nothing to sneeze at -- it would be equivalent to a "D 860" processor following Intel's numbering convention, so I have to say that I am very pleased overall.
