Intel's Nehalem CPU architecture is simply the most advanced in
the world. That's why a quad-core 2.93GHz chip like the Core i7
875K can take on AMD's fastest six-core effort, the 3.2GHz
Phenom II X6 1090T Black Edition and win.  In multi-threaded
applications, there isn't much in it. The Core i7 875K is just
over half a frame per second quicker in our HD video encoding
benchmark, for instance. Of course, with just four cores to the
Phenom's six, the Intel chip is much more powerful on a core-
for-core basis.  It's no surprise to find, therefore, that the
Core i7 875K pretty much monsters the six-core Phenom processor
in software that only generates a handful of truly CPU-intensive
threads. That typically includes apps like games and file
decompression.  However, there are plenty of much cheaper Intel
processors with those very same cores. The Core i5 750 and Core
i5 760 both essentially match the 875K for gaming grunt for over
£100 less.  All of which means that the unlocked multiplier that
comes with the K-s
