If only people would be excited about crunching Folding@home for science on their GPUs, but most people are selfish or don't know the program exists.
The key to reduced GPU prices is to buy them used.
Selfish for not folding? You obviously do not pay electrical bills.
Prices are exactly what the market demands. Sometimes you can get more relative performance for dollar, sometimes not. There is no conspiracy, and people owning cards and not folding is far from selfish.
Expecting free energy from graphics card owners is the only thing that is selfish. Altruism in science is a fallacy.
I logged in just to say...friggin' well-said!
