MSI showed off non-reference Radeon HD 5800 series graphics cards at CES 2010, including the R5870 Lightning and R5850 Cyclone. The latter one uses the Cyclone GPU cooler, while the other one features the Twin Frozr II dual-fan VGA cooler.
Thee R5870 Lightning, as expected features a Twin-Frozr II dual-fan VGA cooler designed by MSI on a custom-designed PCB which makes some high-grade components, specifically in the card's VRM area (12-phase PWM, dual 8-pin PCI-E power input), to make it fare better at overclocking. Other notable features include v-check points and 1 GB of GDDR5 memory across the GPU's 256-bit wide memory interface. Connectivity cluster resembles that of the AMD reference design, retaining Eyefinity technology support.
