Well, my more "online savvy" friends are most likely aware of the two companies. When the NV logo is slapped across multiple game releases, they might start to assume it's better.
Most family members are not, and the few times I've been with them shopping for parts, sales reps definitely push things on them. Had my poor mother almost forced into an Intel laptop for $500 when the the one I knew would cover her needs (an AMD model) was on sale for $200. Pretty sure if I weren't there to tell the rep we already had one in mind she might have walked out with the $500 Intel.
I've lived in a see of green for years. But thanks for asking about my friends/families preferences
