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.

@svl7 need your help here. I'm sorry, I'm little confuse here, I don't see all these was clarify in the first post.

Just upgraded mine with Dell's AMD 7970m after I found out this thread. Basically is just plug and play, except a little grinding & cutting the screw hole of the back plate, apply thermal paste and apply thermal pads.

Thanks for sharing all this wonderful info!
