MSI kicked off its GeForce GTX 770 lineup with two models, the GTX 770 Gaming Series, and the GTX 770 Lightning, both of which are factory-overclocked models. The Gaming Series card (model: N770TF/2GD5 OC) ships with 1098 MHz core, 1150 MHz GPU Boost, and 7010 MHz memory; while the Lightning (model: N770Lightning), ships with 1150 MHz core, 1202 MHz GPU Boost, and the same 7010 MHz memory. Both cards come with 2 GB of GDDR5 memory. The GTX 770 Gaming Series OC features a new generation TwinFrozr cooling solution with large 100 mm fans, and the sexy red+black color scheme, paired with the Gaming Series "dragon" emblem. The GTX 770 Lightning, on the other hand, features the same TwinFrozr IV cooling solution we find on the GTX 680 Lightning. Based on the 28 nm GK104 silicon, the GeForce GTX 770 packs 1536 CUDA cores, 128 TMUs, 32 ROPs, and a 256-bit wide GDDR5 memory interface. MSI didn't reveal pricing or availability information.
