You have a nice build but it's not as good as you think. Just because it's 2010 game it doesn't mean a mid range OC build will max out the settings. Think along the lines of Metro 2033, and try playing that on max settings even on just 1080p.

When you're playing with 690 sli on a 3960x at 1440 resolution and you can't max out settings still then you can complain.

No offense.
