    Hey guys,
    so benchmarks are out there and as far as I see it the 970 performs like 1-3fps worse than a 780 Ti and a 980 around 10% better.
    My current 1,5 month old 780 Ti Matrix is currently sent back because it's faulty, now I have to wait. However I can ask the shop for money back. I've paid 600€ for the 780 Ti Matrix. A 980 & 970 from Msi costs 580€ & 350€. But I would like to have one from Asus so it could match my Asus RoG Rig :)

    The 9xx Series has 1gb more Vram, less power consumption, new features and less heat output.

    I read that a 980 is better than a 780 Ti, but if both are OC'ed the 780 Ti wins?
    Did they do the benchmark with a reference 980 vs a custom 780 Ti? This would be stupid...

    This Benchmark shows that a 980 is stronger than a 780 ti and the scaling of two 970 is huge! http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_970_SLI/6.html

    The last and first time I had Sli was with the 560 Ti series and I had in some games noticeable microstutter, how is it now?
    Is my power supply even enough? For a single 980 of course, but if 970 scale well, microstutter ist almost gone I would really appreciate to have two of those nice guys :banana:

    My current power supply was enough for two 560 Ti's, the 970 shouldn't be a problem since the TWD is lower ?

    Your advice ?

    What I forgot to say, I play on a 1080p@144hz 3D Monitor, some games @ 1440p.

    The 980 starts to pull away from the 970 at 1440p resolutions or higher.
    For the price go for the 970's, if price is no concern go for the 980's.

    Well two 970 would cost me only 100€ more, since they're 2x 350€ each. I would love to have 980, but add one later is no option since new hardware comes like every year and 2x 550-600€ is .. yeah ^^

    Is my power supply even enough for two 970? I mean two 970 shouldn't draw more power than two 560 Ti's.

    Also as I mentioned I play on a 144hz monitor, how about microstutter?

    I'm going to get one Asus Strix 970 as soon as they are available over here, then ive got the option of adding another one later.

    Decided on the Asus Strix as it only needs x1 8pin pcie so i wont need to mess around with any more cables and/or adaptors if I do add a 2nd card.

    This review shows some benchmarks with overclocked 780's and 780Ti's.

    May be usefull

    Yeah, I really think that I'll get two 970's. One is a little bit weaker than a 780 Ti but also 200€ cheaper. And 100€ more for double performance is kinda worth. New driver will bring the 970 more near to the 780 ti I think :)
    I hope that Sli is today better than it was in the past (heat, performance, game profiles).

    But do you think that my power supply will be enough for two 970's ?
    I would say yes because I could run two 560 Ti's and those draw more than a 970.

    Don't worry about microstutter anymore.

    Thank you for your reply.

    Is my power supply enough?

    No. I would aim for at least 850 watt or more.

    What are you basing this on? If I'm to understand correctly, he currently has a 780ti. The two 970's will only be about 40 watts more than the one single card.

    I honestly think people oftentimes overdo the PSUs in their builds. 660 watts peak with dedicated 12v rails will be plenty for his build.

    you don't need 850w to run 970 sli. I ran 7950cfx on my 750w psu without a single problem, running 970 would be less demanding.

    You might get away with a 660w PSU, but it'd be awfully tight, it's not something I'd do personally. I'd aim for 750w at least, as eclap stated these cards aren't that hungry.

    I did a mock-up build based on his signature.

    pcpartpicker.com/user/solomyn/saved/ycFmP6

    Based on this, he would have about 150 watts to spare. Plenty.
