he needs it for a racing game, not for flying planes :lol i love the dell monitors :lol and they have the same headphones in that pic i used to use 
logitech G25 or better will be the best wheel setup / shifter / pedal etc that your going to want to use with iracing for sure
they have more expensive setups but they are alot more expensive over 500 dollars usually, logi g25 always seems the best choice
