what do you think the new prices of the old cards GTX260-285 4850-4890 will be after the 5850-5870(x2) is released? i'm curious because i'm building a new PC soon and i was originally going to buy the sapphire 1gb ddr5 4870 but if the GTX275 drops a lot i will most likely buy it. and the 5870 is scheduled to be released the 22th i think?
