The guys at Tech Report noticed that even though the Quad FX parts are available for sale now, they aren’t the prices AMD quoted to everyone last month. 
Of course, we should point out that neither AMD nor Asus have control over retail prices. Still, at those prices, someone looking to build a machine with a pair of Athlon 64 FX-74 chips will have to pay with a premium of either $129 or $181, depending on the retailer. Considering Quad FX hardware was supposed to hit stores with lower price tags over a month ago, those premiums might not sit well with many users.

We quizzed an AMD spokesman about the subject, and he confirmed that AMD has not changed its official prices on FX processors. We also asked Asus about its motherboard pricing, but the company has yet to answer.
