Any idea when the 670 might drop price

I know there has been some drops but its all very miniscule maybe 5%. When do you think a big drop will come; like how the 570 is only like $250 now when will the 670 drop that much

It'll drop that low when it stops selling at its current price. Except for the 780, Nvidia's new line of GPUs isn't really different... at all. So people still buy the old stuff.

I don't see the 670 dropping below the $300 mark until AMD releases some new cards.
