lol, I get 120 fps in dota, 999999999 fps in cs source, and something high in cs:go all with my i5-3570k stock and my trusty old faithful gtx 570. Why on earth do you need this much tech to run source exclusives? If you want to dual boot windows for bf4 or crysis 3 then cool, but then its not really a steam machine. I think they're jumping the gun. Also, why titan over 780ti? They trying to crunch seti #s or something. So lost....
