TPU reports MSI has revealed the Radeon HD 7970 Lightning Boost Edition. This card has the new "Tahiti XT2" Radeon HD 7970 GHz Edition GPU, while the original Radeon HD 7970 Lightning card had a 1070MHz core and 5600MHz memory, this new model has a 1070MHz core, 1150MHz boost, and 3GB GDDR5 memory clocked at 6000MHz.
Most other features remain the same. The R7970 Lightning BE packs an enthusiast-grade 17-phase VRM, dual-BIOS, voltage-conditioning GPU Reactor module, and TwinFrozr IV cooling solution. Quite shockingly, MSI didn't take the opportunity to address the lack of dual-link DVI connectors in the original R7970 Lightning, the Lightning BE continues to have two single-link DVI, and four mini-DisplayPort connectors. The new R7970 Lightning BE could displace the original from its US $499.99 price-point.
