Currently I'm using ATP 3 speakers and onboard C-Media CMI8738-C3DX 5.1 channel soundcard. I'm planning to buy Creative Sound Blaster Live! 7.1 soundcard. Would this be an advantage over onboard C-Media soundcard?? Now I'm still using 2.1 speakers like ATP3, but after adding this SB Live! will I get good performance from my 2.1 speakers??
