So i dont know whether to get a SuperClocked GeForce GTX 660 2GB or a Radeon HD 7870 GHz Edition 2GB. I would be using it for games like Skyrim, Crysis 3, Saints Row 3, GTA 5, Saints Row 4, Battlefield 3 and other performance intensive games like that. Hoping to get around 60 fps on high or ultra. Which card would be best for those needs? Any help?
