I am building a PC and I need some help. I am getting the ABIT AG8 motherboard and I wanted to get the Audigy 2 Value Sound Card, but after browsing some boards I saw that some onboard audio can perform quite well. I am getting the Creative Inspire T5400 5.1 speakers. Now, should I get the sound card, or use my mobo? If theres not a big difference in sound then I'll save $50 bucks and not get sound card.
