Hexus posted a review on the AMD Radeon R9 290X
A quote from the article:
AMD launched a number of new graphics cards a couple of weeks back. But examining the details showed that the R9 280X, R9 270X, and R7 260X - the three headline GPUs - were largely rebrands of older technology. Countering a lack of genuine GPU advancement, AMD's attractive pricing makes the new cards reasonably compelling propositions.AMD Radeon R9 290X Review @ Hexus
The new, interesting GPU is the R9 290X, built using a brand-new die and designed for class-leading performance. Codenamed Hawaii and intent on a stare down with Nvidia's impressive GeForce GTX Titan and GTX 780 GPUs, today is reckoning day.
