So I've just built my first budget PC, and it is AMAZING. I'm proud of it, but now once hardware is out of the way, there's peripherals. I have a HP 2009M monitor, along with a generic HP mouse and keyboard that came with a HP PC I bought a few years ago. But for gaming, I use a Razer Nostromo. Should I shell out an extra hundred for these "specialized" peripherals, or will what I have make due? Oh and, do I really NEED a headset? I have a pair of Skullcandy Hesh 2 with Mic that seem okay. Thank you!
