It depends heavily on where the OP is based, some parts of the world simply do not do discounts on expensive hardware like GPU, if they do, they probably are clearing out several years old stock.
In US they probably will do discounts, where I am, they are still selling 700 series at MSRP.
Lastly, might take a while for 780 ti to fall to the level of 970's, if they fall. A quick scan through amazon and newegg does not suggest they are falling in price anytime soon.
