The 8GB of GDDR5 is clocked at 8008MHz on a 192-bit memory bus, while the card requires a single 6-pin PCIe power connector. NVIDIA really hit the mid-range champion spot with the GeForce GTX 1060, and for its price point, you're only going to buy the GTX 1060 for 1080p gaming. I wouldn't recommend a GTX 1060 for 1440p or 4K gaming, but rather the GTX 1070 for anything at 1440p - and really, GTX 1080/GTX 1080 Ti for 1440p @ 100Hz or higher. For mainstream gamers who want to tap some of those massive games like CS:GO, Rocket League, League of Legends or similar, the ASUS GeForce GTX 1060 Dual 3G is a perfect card. 3GB of VRAM is fine for 1080p gaming, and even better for 720p or so (hey, some gamers don't have new 1080p capable LCDs yet).
