Asus K53SV Extreme Mod Help

[truth]

Hey guys,
i am enhancing my asus K53SV ( i7 2630qm) with an eGPU GTX 1060 and im planning to buy a better CPU to reduce the CPU bottleneck on the 1060. At the moment, i have a 130W power supply ( 90W stock). I bought a Destkop CPU Cooler ( Cooler Master Hyper T2) to handle the CPU temps and im wondering if a 2960XM would overclock to lets say at least 3.5GHz on 4 cores stable for gaming. I know the stock BIOS wont allow the 2960XM to work but i will update the CPU Microcode to make it accept the 2960XM. So here are the questions :

1- Does the CPU microcode manual update work ?

2 - Can the motherboard, designed for a 45W CPU without overclocking handle 55W+ (lets say 80-90W for the overclocking) ?

3- is a minimum of 3.5GHz on 4 cores stable possible with the 130W PSU, lets say that the motherboard only has to power up the CPu and the others main components (HDD, RAMs, etc), there is no dedicated GPU, so it has way more juice for the CPU alone.
