When the 7800GTX came out, it was priced at around $500. THen they came out with teh 7800GT, at around $300, with lower pipelines and lower clock speeds. I don't get why if a card has lower clock speeds it sells cheaper. Is it cheaper to manufacture a slower card than a fast card? To me it seems that they are spending the same amount of $$$ to make the 7800GT's and selling them for a lower price. Why doesn't nvidia just discontinue the 7800GT's and drop the 7800GTX's to $330 or so?
