Hi everyone! I'm going to be building a new PC soon, and was wondering if it would be necessary for me to get Windows 7 RTM. I have been using the RC for a few months on my current PC, and since it doesn't expire until March, I'm thinking of just using that on my new build. Would I be able to transfer the RC from my old PC to my new PC? Also, are there any major advantages of the RTM version? (Is is faster?, More Optimized?)
