Well, I don't exactly know about getting a reciever as well, I'd rather avoid getting another unnecessary peripheral, I'd prefer a more direct setup, I suppose I'll look around for such a JBL system.
Edit: upon further research, I can't say I've found any computer speaker systems above 2:1 for JBL, I can understand their quality, I've heard of their quality many times. This setup will be used for gaming, yes, and while money is relatively no object, I see little need to spend upwards of $1,500 for what would seem a quality setup for a complete Home Theater system.
