Intel DP55KG P55 Lynnfield Motherboard @ PC Perspective

"Intel helped out their LGA 1156 product line a bit more through adding a few more power saving features to help increase the longevity of the CPU as well as ensure it performs at optimum levels under load conditions. The DP55KG posted the lowest power numbers, which really is a testament to Intel's commitment to ensuring their cores run efficiently and effectively when they are needed most - during critical, CPU intensive applications or other multi-tasking operations."
