+1, as that is minimal, as Win is also installing the PhysX and 3D options.
However, I sometimes wonder if the OEM latest is necessarily the most stable. I suspect that getting WHQL certification to be included for Windows Update may require some more stringent stability requirements, whereas direct-from-the OEM downloads might be more targeted to the ‘cutting edge’ gamers, who are more impatient, and have less stringent real-time audio stability requirements than us fringe market dwellers!
After all, it was gamers that basically drove the GPU market with their ‘money is no object in the pursuit of speed’ attitude for years. Of course, we have to be grateful to them, because we get to have cheap high-performance video cards.
That drive also pushed Intel to integrate much better video into their laptop and desktop chipsets and CPUs than those underperforming and restricted-capability ones, with poorly-written and inflexible drivers, they had been dumping on us for years.
