If you see a website offering you the ability to pre-order a GeForce GTX 470
or GeForce GTX 480
, they are going to be lying. The official word straight from NVIDIA is:
"NVIDIA and our launch partners have not released pricing or pre-order information yet. Any Web sites claiming to be taking pre-orders should not be considered legitimate."
So there you have it. Don't be scammed by companies that say you can pre-order from them or even having a pricing displayed
