Thoughts on improving video edit perf & OC Heat issues

Ive been doing some video edditing/mixing with the Mx11, and I was wondering if there were any thoughts on improving the performance. The software seems to have no option for using the nvidia chipset, and I have a slight OC of the CPU (150mhz, which with the intigrated icore, Oc's everything on that clock..RAM, etc..), but the video is pretty jumpy. running 260 nvidia and the latest Intel as of Dec 6 2010. Anybody whos up on the new nvidia drivers have any thoughts on if they will incorporate more use of the GPU on default (such as aero, video playback, etc), as opposed to using the lowend GPU?

I also was wondering if anyone out there had any thoughts on a DIY heat spreader for the ram.. which as I read seems to be a concern for Oc'ing.. I have looked inside and dont see much room to work with.. but thought I'd put the idea out there- might be able to glue some copper plate onto the stock RAM, which seems to be a bit low end quality ram, so killing it before I buy something better might be worth the risk.

I also have been experiencing a lot of physical heat under the leftside palm rest with a 150mhz OC.. just wondering if I'm the only one.. I have tried with and without the SDcard I was using for turbomemory, and seems to be only a little warmer with the SDcard running..

 

Throttlestop should help out immensely for encoding.

 

Actually TS is running, definitely a great improvement (props to uncle? on that!) on encoding, but the live video preview is just rough using the Intel chipset
