@donkeycow: No one is taking away your video gaming. They're criticizing the things about something THEY don't like. With their words. If I said I didn't like Phillip Glass music that doesn't prevent Phillip Glass from composing. He has an audience and he composes for that audience. I'm still allowed to express my opinion.
You're over building for 1080p gaming. Unless you're going to upgrade to a 1440p monitor, you can easily run games on max with a GTX 670 or 7870. That much ram is overkill. IMO the sabertooth is not really worth the extra money and you need to get ssd as a primary drive. It will be the single biggest improvement you can make.
If you want decent advice, reddit has an active community to rate your build.
