The problem with Driver-Booster and other 3rd party programs is they recommend or even just install new drivers just because a new driver is out there. Unlike other programs, drivers don't necessarily need to be updated just because a new one is out there. If your hardware is working fine, don't fix it. I mean if your network card has been working fine for 3 years, does it really need updating?
Most drivers these days are driver bundles - that is, one bundle addresses a bunch of different models from that maker. Chances are, all the new driver does is add support for another piece of hardware - hardware you don't have. This is very true with chipset drivers - most updates add support for a new CPU or new RAM that came out after the chipset left the factory. If you don't have, or are not planning to buy that new CPU, why install the new driver?
I don't install new drivers unless the readme file says it addresses a problem I am having, fixes a security issue (which is rare), or because my existing driver is corrupt (also rare). Same with BIOS updates.
The only exception might be a graphics card driver as they often add new features and protocols or specific tweaks for specific games. But both AMD and NVIDIA are great for notifying users of new updates.
