Completely wrong. First of all it's impossible to compare the performance of different processors. Some will perform better in one app, and worse in another. For instance the X2 6000+ in some apps is faster than the E6600, E6700 and even the X6800. In very few, it's slower than an E6600. But still, it's about 2-3 times cheaper than the Intel equivalent. Fastest AMD's 2-3x slower than C2D's? Note that the QX is a Core 2 Quad, not a Core 2 Duo.
