According to WCCFTech, NVIDIA might introduce some price-cuts for GeForce GTX 660 Ti cards,
which would happen on the same day GTX 660 non-Ti launches.

This week KitGuru reported that the sales of GTX 660 Ti are very sluggish.
The problem with the GTX 660 Ti price is quite simple,
the fastest factory-overclocked version cost as much as the cheapest GTX 670.
The site has even found a GTX 670 for £227.

Currently the lowest price of GTX 660 Ti is $299, that’s for a fully reference model.
According to WCCFTech the new price of reference-based cards would be $279, while custom models would cost　$315.
That’s still more than Radeon HD 7870, which costs $259. However this decision might give a small boost for GeForce sales.

There is no information about any price reduction for GeForce GTX 670 and GTX 680.
Let’s just hope we won’t see this equation to be true $ = ?.
