I am wondering if I should over clock my Intel HD 3000 graphics and what would be the best method? I have an i5-2500k and the max I ever hit doing a CPU test at 100% for like 47 minutes was 52C. Cooling won't be an issue, just wondering if I would see a bit of performance. I only mainly game Killing Floor and MineCraft. Would like to try it for a bit. BTW CPU is at stock speed.
