Definitely worth installing, since they are created specifically FOR your hardware, and not some generic driver that may (or may not) kinda-sorta work. ish.
Without the VIA drivers installed I had horrendous performance on my harddrives in my old system... And even worse, very unstable - copying any file from the C: to the D: would almost always result in a blue screen of death. All issues went away as by magic after installing the VIA drivers.
