I was going to buy Win7 64-bit Home Prem, and it says OEM. So if I wanted to switch to the i7-3770k in the future, Iwill have to buy another win7 copy? Also, like no support? So if something groes wrong I don't get support by them? I want to be able to do such things. Can I do a clean install with it so no bloatware? finally I am sure it works just like any other OS (no trial, or limitations besides those?).
