    I can get a slightly used, 100% functional i7-2860QM quad core on eBay for $58.00 USD.

    Is it advisable that I attempt this upgrade? My research into this has yielded mostly very murky results...

    My main concern is replacing a 35W TDP CPU with a 45W TDP CPU. Conventional wisdom has it that the 15.6" notebook form factor should handle 45 watt TDP CPUs. I have the latest BIOS (dated 11/2012)

    The i7-2860M is a Sandy Bridge, is a socket G2 / rPGA 988B, like my current i5-2410M CPU, (both work with HM65 chipset).

    I will most definitely have to replace my 90W power brick with a 120W one, and will have to put in new, high-grade Arctic Silver paste on the heat sink.

    $58 bucks for a slightly used, fully functioning quad core / 8 thread 3.5 GHz CPU is irresistible. The seller has 99.89% approval rating on eBay, from 540 buyers.

    My question is: anyone have a rough idea about my likelihood of success? Is it worth it?

    (i've replaced/upgraded many laptop CPUs in the past, all successful)

    The wattage of the CPU depends on the wattage capability of the heatsink.
    Do some research and see if any other versions of your laptop came with a 45 watt processor. if one did, then you will need to purchase that heatsink too.

    Thanks for your reply, Priest-King...

    Question: "The wattage of the CPU depends on the wattage capability of the heatsink." It does?

    Re: getting a 45 W -rated heatsink for my laptop ... wish me luck with getting that!

    Also, my AC adapter is rated at 65W. Other laptops with the i7-2860QM typically have 120W adapters. Again, wish me luck with getting one of these...

    The more I look into this, the more of a bad vibe I'm getting.

    (btw, I know you didn't ask, but just to head this off - it doesn't matter what I "want to do with it" - meaning, this CPU-upgraded laptop. It drives me crazy, all these so-called 'experts' and 'gurus' on these forums who ask, right off the bat: "what do you want to do with it'? None of their goddam business, that's what! I want to type out and sort multithreaded biscuit recipes with it.)
