Nvidia and VIA do come out with more drivers, but in my experience they are rarely "needed". Those who may have some issues with early implementations(hardware and software) may need to Update to newer drivers, but it is very rare that the same person "needs" to Update to every driver that comes out. Like most Hardware companies say, "If your system is working fine, don't bother. If you are experiencing X, Y, or Z, then use this version"
