So I want to get a i7 4770K to replace my Amd FX 8150 I have at this moment. I know when switching from Amd to Intel or vice versa that you have to wipe your hard drive. So I have Windows 8.1 retail with both 64 bit and 32 bit discs. My question is if i can use the key to install Windows again for the 2nd time on the drive once its wiped. Thanks in advance!
