I have a generic keyboard (don't even know the maker name) and a Dell mouse. Regarding the headphones, I use my old iPhone ones, they "do the job" but that's about it. So basically, a crappy set of generic peripherals!

I have a R9 270. The only problem with that card is the temperature I get on summer, but that's a problem with my setup anyway. Waiting for Zen for major update on my rig though. I hope they show up something as interesting as Intel at least and a new card (an Rx480??)
