His CPU is fine and better than fine .
a single 3.4ghz i7 ivy bridge core can handle DCS without any issue.
my CPU is older (Nehalem based) and at the same speed and doesn't reach 90% on the busy core when running DCS.
his GPU on the other hand is weak for most settings but medium at a decent resolution.
in any case, to people worried about DCS 2.0 working slower, i don't think it works like that, pretty sure most people will see an increase in performance or be able to turn on more eye-candy atleast.
