Not sure if penis contest or really talking about computer parts anymore...
No contest.
1 690 beats a 590.
2x 690 is just insane.
Tbh,the 2nd one was kinda a waste of money (from other people's view)
A single card maxes every game I've ever tried at solid 60fps+
The 2nd card is just nice for actually running the same thing more power efficiently (in the aspect that it isnt 1 card under heavy load)
^ thats assuming either of the 2 heavy load games,everything else doesnt even warm up at all
