I bought a GTX 660 yesterday and installed it on my pc. I installed the drivers from Nvidia GeForce experience. My old card was a GTX 260. Now, all the other parts are the same. But for some reason my computer is now painfully slow. At everything, like literally everything, even surfing the web, let alone play games. What the heck is going on?
