Viperlair posted a review on the HIS Radeon 5850 Turbo

he 5850 has gained a reputation for a being a great overclocker and great value for money. With DirectX 11 and Eyefinity support, as well blistering performance that won't overly tax your power supply, it certainly has a lot going for it. Of course, many high end ATI cards come with Call of Duty Modern Warfare 2, and with the 5850's overclock ability, HIS thought it was time to put out a Turbo version of their 5850. The HIS 5850 Turbo comes clocked at faster speeds than a standard 5850, includes a free game and sports the excellent iCooler cooling setup.
