I have to say that 780Ti is somewhat a low blow at nvidia fans. Some people were hit directly in the "family jewels" upgrading from 780 to 780ti. You bough the same thing again! NV charged you twice for the same product (or 4 times if one went SLI both times).
Look at the possible upgrade path this gen (28nm)
gtx680>780(Titan )>780ti
They repeatedly sold you a card for the flag-ship price point, which was not a flagship.
AMD did 7970>290X but that is a bit different, as no one expected big die from them.
The 290 launch was another blow to AMD fans. Some people where hit directly in the "family jewels". AMD charged you hundreds more for the same product. They sold every 290x they could till out of stock only to release the 290 weeks later which performs exactly the same and cost soooo much less. I think I would feel pretty bad if i was suckered into that scam!!!
:whiste:
See it can go both ways. Just saying.........
