Help with Windows 7 setup

[PierreNodoyuna]

Hi,

I have a doubt. I really like to play my guitar through Amplitube in my Windows 7 64 system. Currently I have my Guitar->practice amp->on board souncard through line in. Sounds great. But I like to have an option amplify the sound and I'm guetting a PA System so going to connect the soundcard to the PA system. I'm not intereseted in recording. But I'm worried that if I amplify the sound my current setup is not going to be good. I need an audio interface? for the use i will going to take is any advantage? Also other problem I have with my current setup is that Media player doesn't sound when amplitube is working. When I turn off Media Player strats to work. This is resolved with an external audio interface?

Thanks for the responses!

Basically all onboard soundcard have about 40cents worth of parts and are made for:
* cheapness to the manufacturer
* for beeps and boops (system sounds)
* light gaming

The poor drivers will give you high latency (delays) and poor performance.
Even the cheapest $50 usb asio card will be a huge improvement.

#1 Rule of Recording: You MUST replace the built-in soundcard.
