The HD 68xx range (mid range) are launching in about a week and the HD 69xx range are launching about a month later. Why would you get a GTX 480? You could easily cut down the power supply to the 700W range and even then that would be overkill if you went for something like that.

Saves you $40 and gets you a better brand.
Tease.
