No! Don't even dare to put a 5.1 sound system in front of you!!!
Nah just kidding (the angry mood

) But yeah, if you get a 5.1 system, theres no point if you are just gonna put it in front of you. There's a reason why they call them "Surround" trust me, find a way to put them around you and you will get awesome sound quality, especially from games!
