I didnt want to be too greedy, so I went with the Pentium M 715 1.5. This baby is cooking at 2.0 ghtz. I also went with using some AS5 to cool things down a bit. I have seen about a 5 degree change in my CPU temps and GPU temps. The mod took me about 2 hours to complete. This was my first time opening a lappy so I took my time. I will let you know if I have problems for those that may be interested.
