If you have enough get a SSD for programs and games and a 1 or 2 TB drive for Music, Videos and Documents. I recommend the Crucial M4 series. A SSD made the biggest differents to my PC after upgrading to one everything just loads in seconds saves a lot of time waiting and makes the PC so much...
I use the JVC RX700 and they are very comfortable and sound great. Only thing no mic so you would have to buy a clip on or desk mic.

The CPU is not supported by your motherboard so without a BIOS update to support it there is no solution really. Not sure what drivers you are talking about but it would make no differents anyway.
It's not the movies or games downloads that I would worry about, like breaking into networks, downloading encrypted things, spying on network traffic. I have seen so many "Top Secret" seals on files when I was a kid
I was obsessed with finding UFOs, a surprising amount of US files where stashed on computers in other countries, China back in the early 90s omg sooo much
