MSI rolled out a 4 GB variant of its GeForce GTX 770 Gaming graphics card. Bearing the model number "N770 TF 4GD5/OC," the card is virtually identical to the 2 GB original, except double the memory amount. The card uses sixteen 2 Gbit memory chips arranged on either sides of the non-reference design PCB. The card offers factory-overclocked speeds of 1137 MHz core, 1189 MHz GPU Boost, and 7.00 GHz memory. It features a TwinFrozr IV cooling solution that uses a pair of 100 mm fans to ventilate a large aluminum fin stack. MSI didn't reveal pricing or availability details, but we expect the card to be priced around the $450 mark thanks to its high-performance cooler, factory-overclock, and double the memory amount as standard.
