I took the advice of the forums and got a p8p67 dlx with an i5 2500k but am afraid of how it is going to work on first boot. I am using my old hard drive and have heard that windows imprints to the motherboard. I am running a retail version of win7 home. Not sure if this makes a diffrence. All I have left to do is mount ny new cpu and mobo to my Coolermaster HAF 932 but do not want to have a brick or be stuck on hold in india. Am I over worrying this problem or does this only apply to OEM versions?
