What is the impact of pairing a Core i7 860 on a LGA1156 platform (which supports up to 1333Mhz memory) with 1066Mhz memory (assuming standard timings)? Will the 1066Mhz memory affect the speed of the CPU or other components sat on the motherboard (i.e. are the base clock rates linked)? Or is it purely the memory bandwidth that will be affected? If so, would the real-world performance degradation be noticeable?
