CPU for 1070 Sli

[hellenfort]

Hi,

So my new rig new rig I'm pondering now that Battlefield 1 is finally here:

6700k or 6800k
A descent mobo, say: Asus ROG Hero VII or MSI X99A Tomahawk
Evga 1070 OC SLi
Hyperx 3000mhz 16gb
Evga 1300w
ROG 27'' 1440p

Check this: https://www.youtube.com/watch?v=zvDBnUJi5Bo

Here's some play from the open Beta and the scaling look very good with 100-140 fps in 1440p.

In another video you can see BF1 using All 8 threads on a 4790k pretty hard, and one video also shows a 8 core/16 thread Intel (cant remember which one, sorry) witch every core at 40-50% workload.

Now a more expensive cpu than the 6 core above is out of the question as I'd rather spend that extra cash on the other Gtx 1070.

Are there anything else I should think about?


I'll be gaming in 1080p until new year whenit's time to get a ROG 1440p, but for the time being I'm happy with my 120hz.

Cheers!

CPU load from a game is based on the game itself and on GPU resources available. For gaming I'd recommend the 6700k as many games are still not optimized to use a lot of cores, so with a 6-core you'd have to compromise in some cases.

The Battlefield series has always been CPU-intensive and favoured multiple CPU threads, especially in multiplayer, but that's an exception rather than the norm. The 6700K is all the CPU you'll need for a long time.

Rather than SLI GTX 1070, have you considered a single GTX 1080? SLI can be hit and miss and even Nvidia seem to be shying away from it. Not to mention the additional heat and power requirements.

Thanks for the input, guys!

Yeah, I' hate to use the extra ~ £ 150 on a 6-core if it's not needed. Thing I forgot to mention is my other fave game is EvE Online and with multiple clients open as well as sometimes watching a stream... well, my 3570k didn't like that too much. Still the 6700k is another story and can be OC's pretty sweet, also taking into account that I havn't even OC'd the cpu I'm currently running. So this in mind, do you guys till recomend the 6700k?

About the Sli, as you say a hit and miss. I'll definately take the gtx 1080 into consideration here.

More input would be great!

Thanks in advance

 

[Mr Kagouris]

Yes, still recommend the 6700k.

you do need an i7 to get past 100-120FPS in quite a few games. And for gamer, the 6700K is better ATM.
As for your SLI - it's kinda wasted money. SLI does not work in all games, it is not always supported on game release, it has issues even when supported.
I will not mention that you will have to deal with heat of two GPUs.
A single GTX 1080 is capable of 144FPS on 1440p monitor. So get normal PSU like Corsair RM650/750x or EVGA SuperNova G2/P2 650/750w (whatever cheaper) and GTX 1080.

 

[hellenfort]

Alrighty then.

Heat, noise, bad scaling. Not good to risk. I'm leaning towards the Gtx 1080 and the 6700k which will also save me £££ in the long run and that's really sweet.

Just curious you guys, is 650-750w really enough as I can imagine with gfx card and cpu overclocked I'll easily hit 450w consumption? And from the reviews I read the PSU is most efficient at about 40-50% load? Then again I'm the neebie here and maybe it's all about the quality of the PSU...

(Just a little info though to anyone considering the Evga gtx 1070 OC - the one I got runs really quiet and the fans doesnt even start until 50*Celsius and at full usage never went over 64*c. My jaw nearly dropped, but then again my current dusty 690 is a freaking jet engine on cryptonite xd Still, you can run it with your case open right next to you and you'll hardly notice it purring.)

Cheers good peoples

Come to think of it, I lied: The 1070 hit about 74 degrees in Unigene with pretty much all the stuffs maxed out wich is a fair bit below the threshold of course.

 

[n0ns3ns3]

If you measure power usage during synthetic loads on both CPU and GPU, you can hit something like 350watt on overclocked 1080 and 6700K.
But typical gaming power draw is about 250watt.
PSUs like Corsair RM650x do not spin the fan until 266watt load, so with 650w PSU you are going to get very quite system. And that's is way above minimum. I'd easily use good 450-500watt PSU (for example in small form factor) with that system.

 

[Mr Kagouris]

650W is good enough even with overclocking. Efficiency stays over 80% (and with Platinum or Titanium it's over 90%) at all times regardless of load, and whether you're maxing out the unit or staying in the middle won't affect lifespan because of various technical details relating to capacitor degradation.

tl;dr Platinum-rated 650W and you're good (good choice is the EVGA 650 P2 which can sometimes be cheaper than the G2).

 

[hellenfort]

So I just picked up my hardware and will be returning the EVGA SuperNOVA 1300w G2 for same model 750w as well

as swapping the gtx 1070 in the gtx 1080.

Looking forward to this upgrade!

Thanks to you guys and I hope to give some feedback about performance later on :lol:
