Upgrading CPU and Mobo for first time, anything else I need to know?

I am planning on switching from an AMD chipset mobo to an intel to support the 3770k. This is the combo I'm buying.

Mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131821

CPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16819116501

I have upgraded every component in my PC besides the CPU and mobo before, so I am confident that I will be able to figure out how to plug everything in correctly, but the thing I'm not so confident on is all of the software and driver related issues that can happen from installing a motherboard, especially of a different chipset.

I have heard I should reformat and reinstall windows after plugging in the new components. Should I do this after I test run it to make sure it starts up, or before?

Are there any other concerns from a software perspective when upgrading the CPU and mobo?

Also, here is the motherboard I am currently using. The dimensions are almost the same, but the new one is 0.6" off. Is that going to make any kind of difference for me to have to measure out my case?

Are all of the ports always going to be in the same spot on the case, or do I need to measure that out too?

Thank you very much for the help. I looked around a bit to learn as much as I could, but I want to be absolutely sure this will work before spending the money and risking damaging any part of my computer by improperly installing the new hardware.

I appreciate it!

  1. No. Your new board should fit in your old case. Test the new board first on a non conductive surface, such as a breadboard or the box it comes in before mounting it in the case. All you need to see is a post screen with just the cpu/heatsink/ram/video card. I use a plain flathead screwdriver to start up the system. Just move it around touching the case pin cluster until it starts up. They are all low voltage; you won't hurt anything as long as you have the right cluster of pins.
  2. You should buy a new Windows license.
