Frame Buffer
The Frame Buffer was doubled to 4GB: a gimmick which doesn't yield any performance boost and can be considered marketing to lure consumers into paying more for the same product.
Cooling Solution
MSI’s Twin Frozr V Thermal Designs are equipped with Zero Frozr technology which was first introduced by MSI back in 2008. Zero Frozr technology eliminates fan noise in low-load situations by stopping the fans when they are not needed. Compared to other graphics cards, there is no continuous hum of airflow to tell you there's a powerful graphics card in your gaming rig.
