peetee please stop throwing around insults just because you have a difference of opinion, you've simply been conditioned to believe what companies do like this is ok, your missing the point, companies do this to sell items with a new name that offer little real improvement over the previous model, it keeps the money flowing without any real innovation, basically a few MHz here and there every so often with the odd change in architecture to improve performance is deemed acceptable, its what I call artificial limitation, i can nearly bet it costs not a lot different to have one or two cards at a reduced cost overall but with the mid to maximum performance that year, that way everyone would benefit but at the cost of an overly greedy nvidia.
Nvidia's\its partners' main business is with OEMs, who go on version and model numbers and MB as indicators - they're after profit, hence they'll buy up the low-end 8400\8500 cards en masse, and hype them in "gaming PCs" for silly prices that the average joe will buy.
