With is funny, one 970 is enough to run the witcher 2 on max at 1440p with 60fps.
I don't feel that's a very good comparison. We've already seen titles similar in graphics to TW2 if you use certain mods with Skyrim. Unity with 1440p graphics is no comparison. There's a lot of textures in medieval games that are just cloned, such as trees, grass, etc. Cloning objects is easy now. In Unity there are vast amounts of intricate details and uniquely designed buildings.
I'm not saying Unity is well optimized, it's just a poor example because there is in fact a LOT more detail to Unity than TW2. Ubi have a history of inefficient engines and poor optimization, so they get targeted a lot and in the process people tend to exaggerate.
I remember AC1 being the first game where I started to understand why some people pirate games. Sure it had pretty good graphics for it's time, but it was a resource hog. A lot of people torrented it just to see if their system could handle it. Far Cry 1 was even more revolutionary graphics wise for it's time and ran WAY better, and that was before it was common to clone objects.
