OK so I discovered that the PCIe x16 slot is defective on my board, so It's under warranty and I am exchanging it for a replacement. (same model) My question is, will I need to reinstall my operating system when I get a new board?

It's always advisable to do a fresh install when installing a new motherboard. If you try to boot with the old installation, in many cases it will BSOD before you get to log in.

As for not being able to transfer the product key from one motherboard to the next, Rationale is correct if we are talking about Windows 7 and older. However since MicroSoft did away with the Retail version of their OSes with Windows 8, that restriction only applies to System Builder machines (HP, Dell, etc), you should have no trouble using Windows 8 on another motherboard. You just can't use it on more than one system at a time, just like the older Retail versions.
You shouldn't need any drivers as long as it is the same motherboard, unless maybe it is a slightly different version of the same motherboard.

I RMA'd a motherboard and got it back recently and had to dial Microsoft. They have an automated process where at the activation screen, you can look up the phone number and dial it. The automated voice will ask you how many computers do you have it installed on, and you should answer 0. Then the automated voice will ask you to enter in 20? numbers that are displayed on your screen after you click on get help or contact or whatever. Then it will confirm that you are okay or not and give you 20 new numbers to put into the boxes on the screen to activate.
