In lack of an official announcement (which could still come later today), AMD's Radeon HD 5700 series cards have been launched today via a heap of reviews that show the performance of the first mainstream DirectX 11 cards. Moving from $109 to $129 for the 512MB and 1GB version, the Radeon HD 5750 has a 128-bit memory interface, ATI Eyefinity and CrossFireX support, 720 Stream Processors and GPU/memory clocks of 700/4600 MHz.

The 1GB Radeon HD 5770 has a recommended price tag of $159 and also comes with a 128-bit interface (and also CrossFireX, Eyefinity), but boasts 800 Stream Processors and features GPU and memory clocks of 850 and 4800 MHz, respectively.
