Do I need to reinstall windows when upgrading my CPU & mobo?

Specs: Windows 7, 2.1Ghz
So I'm planning to upgrade CPU from an AMD A6-3500 to a AMD FX-8320 and my motherboard from a Gigabyte A75M-DS2 to something that I haven't decided yet. I also plan to change my 8GB DDR3 1333MHz RAM (kingston brand) to a G.Skill Ripjaws (2x4GB) DDR3 1600MHz RAM and I'll also change my 4 months old generic power supply (because my old one broke down) to a new branded one (currently looking for Corsair and EVGA).
Here is my current build:
AMD A6-3500 2.1GHz (stock fan)
Gigabyte A75M-DS2
Palit GTX 550Ti
8GB DDR3 1333Mhz RAM
500GB HDD

I have been searching and found some answers but there are still questions that aren't answered.

I'm currently looking for a Gigabyte motherboard compatible with the FX-8320 because I want to stick with the brand I used before upgrading hoping that there is a higher chance of me not needing to reinstall windows.

Can you guys recommend me a motherboard compatible with the FX-8320 without having a problem with the old parts? What PSU do you think I should get and how many watts?
I'm looking for around $70 below for the motherboard and around $50 below for the PSU. The prices can go beyond my budget as long as it is not way too much.

Do I really need to reinstall windows? Or should I just backup my files and see what happens after upgrade?

One last question, if the PC didn't boot after upgrading can I put back the old parts and it would boot again? Or will it damage the system?

Thank you!

This PC will never be as fast as yours.

What type of Windows 7 DVD do you have? It makes a difference whether you can upgrade at all or not in some cases.

See the link below for further help.

In the past I have reused WinXP Pro OEM without problem. The official rules were the same as you will read in the link below. I am not sure how MS is treating OEM licenses these days. Hopefully you won't have a problem.

I have a retail one.

You can use a retail version as many times as you wish but you run it on one computer at a time. See the link below.

I am wondering if you can use the migrtion tool by saving settings to a flash drive and then applying them to the new setup. See the link below.

Why wouldn't you just keep your current board & upgrade the CPU? Maybe get an unlocked A8-3870K or A6-3670K & overclock it? Between 3.5-3.7GHz is a fairly typical overclock.

Look for faster RAM 1600MHz or slightly higher.
Look: http://www.newegg.com/Product/Produ...
$54. but $35 after rebate.
I don't follow AMD but it seems to be covered well above.

You have to be a little bit crazy to keep you from going insane.
