If i understood right its 800$ plus A Free Bf copy? Its a good offer for an excellent rig.
One more suggestion here a link it is 800$ not counting the monitor ,it has a slightly stronger processor and a really powerful graphic card,if its about gaming amd's graphics definitely offer better performance compared to Nvidia,but lack durability and are known to use up a lot of power and heat,but nothing a liquid cooler cant solve,also it has G.Skill Ripjaws Series 8GB (8GB) DDR3-1600 Memory,which i think will perform better than the overused 1333 regular ram,even if its 16gbts.But i don't know if they assemble the desktop on this site or only arrange links for you do buy each part separably and assemble the desktop yourself or take it to a professional place where they do that,if so it might not be worth the effort,but if they assemble it this is a better offer.http://pcpartpicker.com/p/9IN3
Good Luck my friend,and may your machine last long and perform well,which ever you choose to buy.
(both rigs will tear,all of todays games and games to date up to 2012,based on most of theirs predicted system requirements,so don't worry even if you have a problem playing a game on ultra somewhere around mid 2013,just buy another 560ti and ram it into sli with the other one and it will tear again,you have a lots of ram,a little bit of an overkill on that side so that will not be a problem for a long long time,and games never seem to require uber processors,so you will be just fine)
