The Core i5 vs Core i7 Dilemma

At first glance, Core i7 laptops look like the obvious winner because they promise more speed and power. But the situation in Nigeria is different. Price, workload, battery life, and generation of the processor matter more than just the name. A modern Core i5 can outperform an older Core i7 in real work conditions.
