New CPU and Motherboard

[guas5373]

I am planning to upgrade to haswell with a new motherboard and and i5 4670k, My question is that if I will need to perform a OS re-install. I am planning to upgrade from Sandy Bridge and current OS is Windows 8 64-bit "System Builder" Thanks!

I did a motherboard swap with Windows 8 and I did not have to reinstall windows. Windows 8 automatically detected the hardware changes and installed the correct drivers.

It is highly recommended.  When I have moved my OS to a new motherboard I had bluescreens and other issues every time.  Most of the time it would not even be able to finish booting up.  But, you can always try it first and see what happens.

Where you switching platforms?

The chipsets and drivers for the motherboard will be different and if you continue to use the old OS you will have some issues. I would do a clean install if I were you to avoid problems.

Would restoring from a back up (a back up of my current not upgraded computer) on the upgraded computer be fine?

Yup, first from a i7-860 to a i7 2700K w/P67 chipset

 

Then from P67 to Z77.

 

have been using it with no problems for quiet a while.

Like your user files? Yes you will be fine because it probably doesn't back up any drivers.
