When will the AMD R9 290x be released?

Just read the subject. I really want to see pricing and performance before I buy a 280x

Nobody is quite sure, but probably in the next two weeks.

I'd guess in two weeks also.

From the part numbers that were given to Newegg I can already tell you that the Asus part number is not a Reference design. The part number Asus gave Newegg is for a Direct CUII cooler and PCB design with the denotation of T for TOP on it in the part number.
