I'm trying to see if there are any performance impacts of going with 4 sticks of 2GB DDR3 vs 2 sticks of the considerably more expensive 4GB DDR3. Most of what I've been able to find are posts from over a year ago on older hardware. I will be running a Core i7 860 on an Intel DP55KG. The memory will be G.Skill DDR3 1600. I don't have any plans for overclocking the system.
