If you don't then you'll wind up experiencing signal delay/latency, and in most cases noise.
Actually what you need is the asio4all driver which you can download free ASIO4ALL - Universal ASIO Driver
So even with the lamest soundcard you can avoid latency.
step 1. download
step 2. install
step 3. configure :
close all runing audio programs
Start --> All programs --> ASIO4ALL v2 --> ASIO4ALL v2 Off-Line Settings
set it up like this
step 4. plug your guitar in your soundcard and enjoy
