GTX400 are pretty useless for now... They don't worth the price and the power consumption... If you really wanna buy a GTX470, you'd better waiting for its price to decrease and for new DX11 games to come (GTX400 seem to be useful only in the case you're running a lot of DX11 applications).
HD5850 / 5870 are a far better choice at the moment.
