[EYEONME]

I was watching a video on YouTube and some guy had 4 x 7970 3gb, he says its my trouble than its worth? Why is that?!

-loads of power used
-tons of heat
-noisy
-gonna need a very very high end mobo
-you cant fully take advantage of three cards (on most mobos) never mind four cards!
-probably driver issues
-most likely games were not designed/drivers for four cards.
