1440p: 980 SLI or wait for 980 TI

[BCShak]

I got my ACER Xb270hu and it's AMAZING, but the new resolutionis a bit taxing and I'm getting FPS in the 30 - 60 range.
My 200 mod skyrim is 25 - 40; SoM: is 40 - 60, Heaven gets around the same.
I play games from all around and Witcher 3 and Arkham Knight are on the list.

I like my eye candy, but I'd stable performance. I'd like to maintain a minimum of 40 fps.

i7 4790k
MSI 980 Gaming 4
16gb DDR3 1866
1300watt EVGA PSU

I was excited to see the 980 Ti with a potential release of June thats been pushed to Sept.
I'm sticking with nVidia so the question
Should I get another 980 or wait for the Ti.

People say the 980 will drop in price but I doubt it will drop THAT much (<$400) and the Witcher is included so that would really be a discount. It seems like now would be a good time.

BUT the 980 Ti, with 6gb VRAM seems like it will hold for a LONG time. Seeing the benchmarks

I'm not sure how much of a boost the Ti would give.

Any thoughts?

Many thanks

I think you'll be fine with another 980. I had two in SLI on 1440p and they had no issues blasting through games on max settings. I dont think you'll need the extra VRAM for a while. Unless you want to move to 4K.
