They remain relatively competative in a more budget concious world. For example a consumer wanting decent bandwidth for their PCIe interfaces, and a reasonable performance is probably going to go for a 1055/1075T, a CHIV, for about £320-340. A decent i7 board is going to run £200+, plus an i7 950 which is £220 ish.
I agree that they desperately need to update the K10 architecture (I'm pretty sure Helen of Troy had one). But for massively multithreaded programs, the AMD is still a smart buy.
