I fear I do not understand. Do we talk chips on the mainboard or chips on the graphics board here? My mainboard is by Asus, my graphicsboard is an Nvidia-based one by <don't know right know who build it>.
For the graphcis board drivers I use to go neither to intel nor to Asus, but nVidia, of course - or not?
My sims and games still run without visible faults, btw.
