Just a little heads up if you plan to go the pre 2012 disc route and still want to use your store content. I decided a while ago to start playing with S3 discs as trying to play through origin with constant windows updates totally ruined 3 for me. My first bit of advice after getting hold of the pre 2012 disc is turn your internet off when you are downloading the game as despite mine being downloaded to a seperate win 7 OS without an internet connection after going online just once on that hard drive to download a couple of apps I needed caused me to occasionally get the game flagging me to go online despite me not being online I have no idea why but better to be safe.
I also found I had to redownload the whole of my store content just using my pre 2012 base game disc and back it up because the store version I was using to play my digital game through origin would not work with my disc game as apparently it's coded differently. It is pain but at least you don't have to install the entire series to get your store content just the base game.
I think i also remember @igazor explaining that it was not possible to install both the disc version and the digital version of the game on the same hard drive as they would try and conflict. I think this could work the same with store content so i would suggest you keep them on separate hard drives or completely delete your origin and just use your discs but i have saved both the digital and disc versions of the store in case a future miracle happens that once again allows me to play 3 on windows 10 but I won't hold my breath :)
