While PC architecture is moving inexorably to multi-core architectures,
one has to question the value of quad-core on the desktop right now,
especially in a gaming system. As we said in
e-2-Extreme-QX6700-Kentsfield-Quad-Core-/p2 our Core 2 Extreme QX6700
review at the start of November, applications are only just starting to
be optimized for dual-core, let alone quad. The fact is that for the
gamer, right now a dual-core X6800 Extreme is the fastest CPU you can
get due to its higher clock speed (2.93GHz vs 2.66GHz).
