So before the 900 series was announced I was planing on buying another 780ti so I could sli them to run my new monitor the 34UM95. Since they said they will no longer be making the 780ti and the only place I can find them is Amazon for 600 dollars, my question is should I just go for two 980s? The 4gb vram would be welcome addition. Let me know what you think.
Go with the 980. The new features and the extra VRAM is nice.
The 980 is faster than the 780 Ti, and with a nice OC can become even faster. OC to OC they are about even, but with a custom BIOS, that may change.
That said, what resolution are you running? If you're running 1080p, you are better off with a 970. There is only about a 10 - 12 FPS difference between the 970 and 980, which isn't worth an extra $200 - $250 at 1080p.
