Median income in some eastern European countries in between 300-500€/month, 2000+€ graphics cards probably don't sell well over there.

Not only that, but outside of the U.S. consumer credit is not always as easy or convenient to achieve as it is here. That means that even in relatively wealthy European nations with GDP's per capita similar to the U.S. people often have "less stuff" and older cars.
When I grew up in Sweden, it was very rare to see people driving new-ish cars. Most people had 5-10 year old models, which they bought in cash, used. Most new cars were business vehicles. In large part this was because financing just isn't the same there as it is here.
While even middle class Swedes do have an obsession with boats, and secondary small vacation homes/cottages, a lot of the excesses we see here, I just didn't see when I was growing up over there. I never knew anyone who had dirt bikes, or project cars they took to the track, or fancy stereo systems with big speakers, or anything like that. It just wasn't something that was common.
Also, consumer goods tend to be cheaper here in the U.S. in large part because it is a larger market, so economies of scale work to our advantage.
I remember participating in many tech forums and IRC channels in the mid to late 90's from over in Sweden. I was used to having PC's that were a generation or two old. I remember being shocked at how many people in the U.S had the
just launched Pentium II's at about the same time I had just upgraded from a 486 to my first Pentium.
I think the combination of more easily accessible credit, and generally lower prices on tech and other consumer goods due to economies of scale are responsible for a lot of that effect, even in countries with similar income levels as our own. Then once you look at eastern europe that equation becomes a bit tougher yet due to income disparities.
