Nvidia have annoyed me with the 7xx series cards just being rebrands of last years cards.
I will however be buying a new card before the year is out but I don't know where to go.
I have always planned of going with Nvidia just on the basis that they have always been well ahead of AMD on high end cards from everything I have read.
Now I feel I would be being ripped off by buying Titian for the ~5% gains but then screwed over if I brought a 780 seen as it is the same card but just artificially tuned down?
If you are going on bang for buck there is not a huge difference between the GTX 780 and HD 7970. Below is part of the Heaven 4 scoreboard.

In the table above people are using HD 7970s like this

And here is a ref GTX 780 to compare

Compared to a Titan, the GTX 780 is actually tuned up (Higher clocks bring it to within 5% of the Titan).
The GTX 770 may be a reworked GTX 680, but again, value for money they are pretty good.
When you are gaming, the game does not care if it is last years model rebranded, it's all about performance.
