I already called and confirmed the stock, the part is brand new, fits my budget, etc... My question is, will this be a plug and play? Or will I have to do some customizing? Also, is that CPU recommended? They have others that they said will work for my machine too, like a i7-720QM, but I wanted the i7-820QM, I just don't want to have to change other parts. This is something I plan to do myself so I don't really know what to expect. Never really upgraded my CPUs before, but I feel confident enough to try this. Any feedback or advice is appreciated. Thanks!
