I have a lot of pro audio experience dating about 10 years ago but my life moved in a different direction so I'm a bit lost. I want to achieve sub 10ms latency with guitar rig 3. I have an HP pavillion dv9000 laptop with conexant hidef audio. I'm thinking about buying a usb audio adapter with ASIO drivers. I'm going to be using this pretty much for screwing around on my guitar. Can anyone help me on the cheap? Or will it even make a difference?
