<< Nobody video card should ever be worth more than $250 to begin with. >>
Well, maybe according to what it's worth to you... but the market certainly is responding to the current price for the highend cards.
Like i read somewhere one time... it takes a lot to make a videocard... requires teams of engineers, a very technological fab. plant, technical support staff, driver support staff, and a lot more. Yet leather jackets, that come from the skin of a dead animal, cost the same as a videocard, and often more... do you think it takes as many designers to design a jacket as engineers to make a card? or what about a fab plant? Ever see a leather jacket that needs a support staff to deal with compatibility issues? But it's not just leather jackets, look around your house... a coffee table, a bed, desk, etc.
Not like i upgrade with every nvidia generation (about once every other), but $250 for a current generation card is definitely a steal. $400 is a bit extreme, but i guess there are different people out there.
