OCIA.net has posted their review of the MSI R5670 Cyclone 1G Graphics Card

Launched in January, the Redwood core represents ATI's third chip in the Evergreen series. Using a 40nm die size, coupled with only 64W peak power, 14W idle, and a sub-$100 price, the 5670 is poised somewhere between the previous 4670 and 4770 in performance. MSI offers three versions of the 5670, a 512Mb card, a 1Gb card, and the one we have for review today, the 1Gb Cyclone. Although all three cards use an improved cooler rather than the reference single-slot design, the Cyclone ups the ante with a dual heatpipe arrangement similar to their 4000-series high-end coolers.
