It's funny though, that some of these websites that are just driving traffic to some paid driver-updating service or product, very often can be used to find a newer driver because they will maintain and display listings of devices by PCI Vendor, Device, and Subsys ID. And sometimes, will even link to driver versions on OEM websites such as from Dell, HP, Asus, and the like. Or someone posts a comment to the page with links to drivers, if comments are accepted.
Best is to just go through to the device properties of each device you want to update, locate the HW ID and search the net for those strings to find the device/chip vendor, the chip model, and whether it has a SUBSYS assigned to a particular OEM or brand.
One of these years, I've been meaning to do a good tutorial on how to do this....
