This should be pretty simple. My current system is as follows:
CPU: Intel i5-750
Motherboard: ASUS P7P55D Pro
GPU: EVGA GTX-680 SC edition
OS Drive: Samsung 830 Series, 256 GB
Data Drive: Samsung HD103SJ
PSU: Corsair AX750
I just purchased:
CPU: Intel i7-3770k
Motherboard: ASUS P8Z77 V Pro
^These will be the only two items changing.
My current OS is an OEM copy of Windows 7 Pro 64 bit. What is my best option for re-installing Windows? I realize that once I re-install Windows on the new hardware, using my current key, I will fail the validation process once it has to activate online. So... Can I avoid buying another $120 copy of Windows 7 OEM? I saw somewhere that I can just use an upgrade key once it's installed (Something like this). Is this true? Because if it is, that saves me about $35.00... I'd still rather it be free, but it's better than nothing.
I get the point... So one more thing. Once I install using my current disk, I have 30 days to activate it right? Also, Windows disks and keys are not tied to eachother right? Like, I could use my old disk to install, and then buy a new license (disk) later?
