Hi there! I am using Guitar Rig with my motherboard soundcard and it sucks. Guitar Rig only works with asio4all. But i only get output form guitar rig, all other outputs are muted (no sound from spotify, windows media or youtube) .
Don't waste your money with crappy Logitech speakers. You want monitors if you are looking into better quality in music (keep in mind that they are more analytical, but it doesn't mean you can't enjoy them). I suggest getting the BX5 D2 ($220), or the AV40v2 ($140), or getting studio headphones like the ATH-M50 or Shure SRH840 for approximately $130 to $200. As for sound card, try the FiiO E10. It's like an external sound card, only better than your Creative Labs products. If you prefer internal sound, consider the Asus Xonar Essence for $210. Don't expect too much out of them if you plan on using them for gaming, otherwise for music production or better overall quality, these are the way to go.
Hi- Unless i'm severely mistaken, Guitar Rig (the hardware) IS a soundcard.
