I want to setup a new PC. I will use it in general for gaming, 3d application/animation (blender etc) and compositing. I have no fix setup yet, but roughly it's gonna be like this :

mobo asus x99 series (maybe asus x99 deluxe II)
ram 32gb or 64gb corsair dominator
vga 2x asus strix gtx 980 ti
2x ssd
2x sata

For the CPU, which one is better in my case : 5960x or 6900k ? So far the benchmark showing 6900 is faster. Price differences in local market here is only around $50. With that price factor, i'd like to go for 6900k but i'd like to know any other parameters to consider 5960x.

Another question is the PSU , how many watt do i need? for that dual gtx, i'll need around 850w, so how many for the rest? what is the minimum ? is 1000w ok?

Anyone has any experience ? or anything to share here.

Thanks.

I would wait and see what the benchmarks for the Ryzen CPU's look like before making any decisions. They are due to be released March 2nd and AMD is claiming that the flagship model will outperform the 6900K at half the cost. You might as well wait on the release of the Vega GPU's, too. I wouldn't recommend using 980 Ti's in SLI at this point. A single high end graphics card will beat the 980's in most benchmarks.

Thanks i will check the ryzen. Btw about 980ti , i choose it because the price of 1080 is $170higher than 980ti here. Even 1070 is still more expensive than 980ti here. But all still in consideration, the options is 980ti or 1080/1070.

Any good reason ? i checked they're quite similar. In some games sli 980ti wins while in other games , single 1080 wins. I watched some review on youtube :
https://www.youtube.com/watch?v=IR8K54n7bI4
https://www.youtube.com/watch?v=aHwI2Zkm6wE

also because i'm gonna use it for 3d rendering (blender), i review it here :
http://blenchmark.com/gpu-benchmarks
and this is how the score is generated :

Those above videos, make me think to get dual 980 ti compared to 1080. But if you have any good reason pls feel free to share here, maybe i can get some new information here. Thanks a lot.

i maybe can not wait for 1080ti. The decision has to be made within 1 or 1.5 months because i'm preparing for some projects. The schedule starts in the next 2 months. Also ryzen is new, i maybe have to wait longer to get confirmed that i will run smooth on my app (software and hardware compatibility issue etc) . I also heard about that 1080 ti , but i'm not sure about its fix schedule release.

Actually you are wrong: the GTX 980 SLI completely destroys a single GTX1080 By a fraction of the price and 2 GTX 980 Ti's will blow smoke out of a single GTX 1080 when going head-to-head. The GTX 980 SLI outperform the GTX 1080 in Almost all games, with the exception of Witcher 3, the 980 SLI was faster than the 1080 at both 1440p and 4K. The 1080 outperforms the 980 SLI in Witcher 3 specifically because the 980 SLI does not scale very well with that particular game. Thus, there are some situations where a single 1080 is advantageous to 980 SLI. Nonetheless, there are a lot of games that do scale well with 980 SLI and, in those instances, it smokes the 1080. And 2 GTX 980 Ti's are A lot More powerful than a single 1080. Actually the GTX980 Ti single card is just 12% / 10% slower than a GTX 1080.

in rendering as i attach link in previous post (blender 3d benchmark) :
http://blenchmark.com/gpu-benchmarks
2x gtx 980ti are better than single 1080.

Here's the result so far :
BLender 3d rendering time (lower are better). I don't what happen to 4way of 1080, it's slower than 3way 1080. But look how dual 980ti beat single 1080.

mode | 980ti | 1080
----------------------------
single | 74 sec | 69 sec
2 way | 37 sec | 37 sec
3 way | 29 sec | 21 sec
4 way | 19 sec | 24 sec

So, again if you have some prove or any facts to support your opinion , pls share it here. I'll be glad to see it as it will help me to decide. Thanks.

Nobody is gonna argue that 2x 980 ti's is worse for blender than a single 1080, we're just looking at it from the perspective of gamers, where it's usually better to eschew the hassles and drawbacks of SLI in favor of the extra stability of a single, more powerful GPU, even if it means giving up some raw performance. One of the questions you need to ask yourself is how seriously you're going to be taking the animation and compositing. If it's your job and the time REALLY matters to you (as in 30 minutes of extra rendering time here and there will really impact your workflow), then maybe the SLI setup makes more sense. However, if this is more of a hobby, then I'd personally go with a single 1080 or even a single 1070 and try to make a smaller build that doesn't take up so much space and power. I have a 980 ti and will be the first to tell you that I'd happily swap it out for a 1070 if it didn't cost me anything. IDK, I guess it's turning into a rant but all I'm trying to tell you is not to spend 100% more money on 50% more performance if this isn't going to be the difference between making a project deadline or not.

buying an 8-core intel cpu seems like a waste of money when you can get a 1800x for half the price. On the 980ti's in sli, it is usually better to get a single card because of lower heat output, and that a lot of games don't scale very well with multiple gpu's.
Nvidia is hosting an event in a couple of days where it is expected that the 1080ti will be announced. That might be a better option.

He stated that the PC is going to be used mostly for gaming, are you even reading what he is asking for?

Here you have a list of 31 pages of games that Nvidea optimized for SLI. Stop arguing nonsense I have 2 main computers at home the one I'm using now with EVGA FTW GTX 1080 and the one my wife uses to play her games with 2 GTX 980's. I get better FPS on my 980's in every single game we play. The only downside is power consumption and heat, my answer to that is who cares about that? when you get almost as twice better performance and newer computer cases have more than 5 fans and water cooled options. I'm getting another 1080 to SLI mine pretty soon and I play with a lot of friends and they all go for SLI when $ is not an issue. There are 2 types of gamers the ones that argue that SLI doesn't work because a website told them about it or the real gamers that try things out for themselves. Same with people saying u have to mix 2 identical cards. One of my my best friends we went to school together for computer science he is running a 4GB GTX 980 with a 4GB GTX 760 for physics nothing to see here move along.
