the 7970 is the best choice of the 3 cards mentioned. the 7950 uses the same gpu as the 270x and the 7970 uses the same gpu as the 280x. just rebadged, and clock speeds are different depending on manufacturer.

yes i would go with the 280x/7970 witch ever is cheaper but a 280x/7970=Tahiti XT 7950=Tahiti Pro 270x/7870= Curacao XT/Pitcairn XT same chip with different name.
