Lag spikes on a fine PC

[KHg8m3r]

PC games and Dolphin are two very different programs. PC games rely heavily on the GPU, while Dolphin requires strong single-core performance on the CPU, using only two threads normally, three max if you have DSP on thread turned on (although its been giving slowdowns recently)

Your current CPU is ok for dolphin. Its not the best for Dolphin, and is behind current Intel CPUs in single-core performance. At stock speeds, the single-core performance is below an i5-2500k.
