Looking around at some Laptop CPUs

[admin89]

Since you P.Med via youtube , I will answer here :
400$ for an i7 2720QM is too expensive
Arctic Silver 5 can conduct electricity , you should buy Arctic MX-4 instead (and it's much better as well)
Your laptop is not a gaming laptop . Beware overheating ...
If you have already decided on CPU upgrading , choose one of these options :

ES is cheaper than OEM
