AMD Phenom X4 9850, 9750 and 9550

Those into massive multi-tasking or highly threaded applications will benefit the most from a quad-core processor, but even with AMD's massive steps forwards, we still feel the Q6600 is the slightly better purchase, regardless of the small £10 price difference. Both can be overclocked, but the Phenom X4s are much hotter and less tolerant to heat in comparison. At just over 60˚C our Phenom at 2.8GHz was stable, but at just under 70˚C it locked up.
