I don't think anyone said its "no any good". Just depends what you do with your comp. It won't help game performance as such, but it will be great for somone running the game server and a client on the same machine for instance. It won't do a thing for office workloads, but then, what CPU does ? And it will probably be very good for media encoding and 3D rendering stuff. Not too mention, Folding, for those that care.
Personally, I wouldn't mind getting one, however, I would *not* be willing to sacrifice single threaded performance. That is just paramount to my usage. Therefore, intels dual core will probably "suck", but a dual core 2.4 K8 wouldn't hold me back one bit.
