I was thinking since my 3570K has Intel's HD 4500 integrated I was wondering what is better to have the second monitor on: the nVidia 460 or the integrated? Do games take a hit by having both on the same discrete card? Does the integrated Intel graphics take a hit from general CPU performance? I suppose I could just switch and see what happens, but was hoping someone here has tried this already.

TiA,
