R9 280 2 monitors?



I am getting the Athlon X4 760k which is a 4 core at 3.8.
 


That's actually a very good CPU.

I used to have that for my very first gaming build.
 
Will there be a big temperature increase running dual monitors?

My 6870 temperature rises when I use dual monitors by 10-15c and I heard it was only a problem with AMD cards?
