Upgrading laptop CPU V120 to N660/P860

[magiccoupons]

Thinking about upgrading my Acer Aspire 5251-1805 currently with a v120 single core 2.2Ghz processor and 3GB of ram to either the n660 dual-core 3.0Ghz or the p860 2.0Ghz triple-core.

The thing is though that on this page they seem relatively similar in speed http://www.cpubenchmark.net/cpu_lookup.php?cpu=AMD+Phenom+II+N660+Dual-Core
and the n660 is 35w instead of the v120's 25w outage that my laptop is used to.

Does the 10w increase really matter however as long as I apply some quality thermal paste? Though I just checked Piriform Speccy and it says my Motherboard and CPU are around 89/90 degrees Celsius, that doesn't sound good to me, and my CPU's average is around 90 :S

And just while on the subject, in my belief processor speed matters more than number of cores as not all applications utilise all the cores, is this near about right?

Sorry for being n00bish.
