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.
