Something to keep in mind as we head into Dec and early next year...
The new 580s just hit the street... I own one and upgraded from my 480 as it was still under the store return policy. There is little doubt that Nvidia will release 560s 570s to compete with ATI's lates releaes of the 6800 series...
These cards if they use the revamped GF110 with disabled features you're looking at signifigant advantages across the board. Add in the cost factor of these new chips and Nvidia is a very good position to take more from the mid market card arena. Just looking at the raw numbers a 570 would be 29 percent faster than a 470 at a much lower price point. That would be faster than a 5870.
