I do not have statistically significant evidence, but as another data point I have the same experience: both my home and work machines are 7-8 years old and work just fine (30" monitors, decent performance with numpy, MATLAB, compiling, perfectly fine graphics, etc.). But around 2000 I remember always carefully looking at the system requirements section of games to check which of those would work on my 2-3 year old computer and for which my machine is too old -- and find a significant rejection rate (25-50%).
