Is the GTX 1070 memory bandwidth enough?

[Lord Flashheart]

Hi

PC Spec: i7-3770k @ 4.4 Ghz 16 GB DDR3 1600Mhz memory, GTX 970, GTX 670 for (CUDA/PHYSX)

I am looking at maybe updating my gtx 970 to a gtx 1070.
I have a 1080p 144hz gsync monitor
My preference is for high frame rates rather than very high resolutions.


It has 8GB of memory which will definitely be enough.

For some games, it will be great, others possibly overkill. That is fine as I want headroom for good frame rates and demanding upcoming games.

For some games, I will want to seriously up the AA options, using the nivida control panel & nvidia inspector.
My understanding of AA is it helps provide the illusion of higher resolution.
I think it needs a lot of graphics memory bandwidth.

The GTX 1070 it seems has 256GB/s onboard memory bandwidth GDDR5.
Is that enough for maximum AA options such as 32xS through nvidia inspector.

My understanding of how Anti Aliasing is limited so are looking for useful info especially concerning GPU memory bandwidth.

AMD cards have GPU bandwidth higher but like games with physx/flex so its nvidia only for me.

Thanks
