Actually, it's not always the price. Serious developers or seasoned computer enthusiasts doesn't change rigs every couple of years. If one's system is performing well enough, and the user gets used to it, system upgrade can be deferred until some technology or computing resource becomes necessary. When something breaks, the broken part is replaced and upgraded in most cases.

Personally, I've just upgraded from 1680x1050 to 1920x1080. My old monitor was 10 years old, and was performing relatively well. I bought a new one, because it started to show its age (mostly backlight age).
