The GTX 670 is not overpriced, it is priced exceptionally well for its performance and for being one of the most high end cards available. It performs about on-par with GTX 560 TI SLI and has a price to fit that and its feature list. Also, if SLI/CFX is what you want, then I'd sugesst getting two Radeon 7850s, not two Nvidia cards right now. Once a card comes out that competes with the Radeon 7850, then I might recommend it (assuming that it competes well and is priced to fit), but the 7850 is a much better card than the 560 TI and in many cases isn't priced too differently.
