Better graphics on p.c really? i thought it was the same as consoles on a 1080p tv?
No. Even if either console was capable of rendering anything but very simple scenes at 1080p (They aren't) they have very dated hardware that simply isn't as capable.
Example: http://www.youtube.com/watch?v=1DLchrdsfAg (Make sure you're streaming that at highest quality, while the difference between console and PC is fairly major, watching it in low-quality footage at low resolution will be difficult to truly appreciate)
The resolution on PC is higher, with more anti-aliasing, bigger textures, better shadows, shaders, and view distance, at a better framerate. The extent to which the average PC is better than a console is almost farcical.
Most PC users consider having to run games at 30fps barely being able to run the game, 60fps is standard and much smoother.
That a PC is more capable than a console isn't even up for debate, it just is.
edit: And yeah, WEI is total rubbish - even if it reported consistently it doesn't actually tell you anything, you can't rate a PC on a single scale!
