So I've really been considering to start to save up to get a 10000 dollar PC. It then I though, what can I learn/Do that I could get the most out of it.
You could learn to budget yourself better. : P
Really, I can't think of any normal situation where someone would need to spend much more than $2,000 on a desktop computer, unless they had some very specific business-related need for specialized hardware (assuming we're talking US dollars here). For programming, you might not want something excessively powerful anyway, since you might have a harder time determining whether the software would run well on other computers. Really, If you could even figure out how to fit $10,000 worth of components in a single computer, I doubt you would be able to use it "to it's full potential", and it probably wouldn't be any more useful to you than a computer built for under $2000.
Also, a faster computer isn't necessarily going to make you any better at animating, filmmaking, programming or so on. If you were into those fields, you'd probably be better off spending money on other devices related to those things anyway. Like a good camera, or a Cintiq graphics tablet, or maybe a vehicle of some sort.
