why is there such a big difference on crysis but nowhere else?! lol
ikr i just bought the 270x hours ago when i could have gotten the 280x for only 20$ more i should have done my research first :/
got to remember 270x is meant to be a cheaper budget card
I got the 270X before I found this site, itmakes me sad I didnt get the 280X xD
the 280x for the most part defeats a 770 card within a few frames.. By far the 280x is the way to go.
