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.
@omghisam: Really? I thought the @ callout was the only part of the notification system that had survived the switch.
I and a few others have been grumbling about the activity feed, but I believe the agenda for Dave, Alexis and the engineers was to make sure GB was working before moving onto Comic Vine's similar make-over. I guess once that's done (after they make sure it works) they'll come back and start restoring our beloved notifications, friend activity feeds and followed blogs side-bar. It's kind of unsatisfying to post all these things into a vacuum, the best efforts of ZombiePie to highlight everything he can notwithstanding.
I received this callout notification but not the original one from the blog post. Weird.
If it never gets fixed you Brits can go all gamebomb and start giantbomb.co.uk
