I want to get another monitor for editing and gaming and such, and i want to hook it up via dvi. But i will get a dvi to hdmi adapter bcuz my 680 has two dvi ports and only one hdmi port. I have the Gtx 680 4gb. How will this affect its performance. I can always set my mobo to performance mode in the bios. But its not preferred that i do so. So what do you think will happen to the performance?
 
Solution
If you only game on 1 monitor, and use the 2nd one only for at the desktop, it will have next to no performance decrease. It may cause one of the cards to run hotter at idle, but that is about it.
