I have a pair of Turtle Beach XP510 headphones and I'm planning to get some 2.1 speakers for around $100 (Logitech, ect). Would it be worth it to get a dedicated sound card or will motherboard on board audio be enough? Not sure which motherboard I'm going to get but it's gonna be one of the newer Z97 micro-atx motherboards. Primary use is gaming, music, movies. Thanks.
