Your awaiting mixed opinion comment was definitely correct!
I would not personally recommend the use of a 3rd party program that updates drivers for you. Some of these programs, if not all in most cases, do not always offer the latest drivers. Said drivers can also be buggy as well, and these programs do not also offer firmware updates, which in some cases are very important. I would recommend always manually checking Intel's site to make sure your chipset drivers are up to date, audio, the works (except video card and such, you'll want to go to nVidia's site for that).
Question, do you use an SSD? If so, make sure it's on the latest firmware.
