I upgraded my home computer recently with a fresh install of Win7-32. I didn't load any mobo or video card drivers. I'm not gaming and otherwise the machine seems to run fine. Should I load drivers from the mobo and video card manufacturer, or is it sufficient for Windows to retrieve what it thinks it needs? This machine has a Q9400 processor on a Gigabyte GA-EP45-UD3R motherboard and a MSI R4670-2D512 video card.
Likewise I just built an i5 machine for my office with Win7-64 and did the same thing- let Windows get the drivers that it wanted. After the install and connecting to the internet it did retrieve a specific driver for the video card. This machine has an i5-750 on a Gigabyte GA-P55-UD3R motherboard and a EVGA 9500GT video card.
