not trying to argue, juts bringing it to your attention.
SLi GTX 570's is quite optimal to me anyways.
I run similar set-up to that with SLi GTX 560-Ti Hawks.
if you have the CPU strength then micro-stuttering is minimal is existent at all.
what are your specs and I will look for links little bit later when I get on-line at home.
i7-930 @ 3.8
ASUS GTX 570 (not the DCU II card)
PSU is currently Thermaltake 750W, but that is going to get replaced if I go SLI.
The heat and micro-stuttering is what has me concerned. Given the cost of another GTX 570 + PSU, I am thinking I will just go to a single GTX 670 solution.
I was just looking for some more info on micro-stuttering.
