Copying Battlefield 3 files to new machine

Im upgrading my Processor from Intel Q9550 to AMD FX 8350, so its surly going have to format my C drive, and re-installing Windows 7 again.

While my Battlefield 3 setup (origin) is on D drive.

Will it still work when I re-install win 7 again ? Or Do i Need to take any registry backup, if any how.

Please guide me. And I hope when re-install Origin again on new machine the copied files should work.

More details. My current Origin path: D:\Program Files (x86)\Origin

  1. Take backup of Battlefield 3 folder (That is inside Origin).
  2. Install Origin client, start downloading game, and then pause. You can see it made new Battlefield folder.
  3. Delete the new battlefield folder, and just replace with the old one and resume downloading.. it will start installing the game and done within a minute.
