My CPU and GPU score drop tremendously in 3dmark11 test, after I upgrade my CPU from 720QM to 920XM, what might be gone wrong? I haven't done any overclock thought, unless this was done in stock. Is there any overclock guide? Am I right that, I should be flashing the GPU vbios to 0.975v, then everything should be better? Anyway I'm using the stock 150W adapter.
