Is it safe or any better to have 2 gtx 1070s in one build?

[Andy_96]

I have a desktop that currently is running on one nividia GeForce GTX 1070. I'm trying to have a crazy build so I'm wondering if having dual 1070s is any better than one or if there's any risk to my motherboard or any problems that might happen in general if I have dual 1070s.

My specs
Motherboard: asus h170 pro
Processor: intel quad core i7 6700k
Ram:32 gigs of ram from adata
Graphics card: nvidia GeForce GTX 1070

It depens if you have mor than one monitor, you could do one for each graphics card. Also make sure if your powersuply can stand another. I think you should if you have the money or the card!!! 😀

[strike]Two GTX 1070s shouldn't pose any problems as long as you have a PSU with enough wattage.[/strike] Actually no, your motherboard doesn't have SLI support.

You should get a non-k CPU with your motherboard as it isn't an overclocking chipset. If you want to take advantage of your CPU, get a Z170 chipset motherboard.

I'm not sure your motherboard supports sli. Reading the specifications it has 2 pci-e slots but one runs at x16 and the other at x4. If I remember correctly nvidia requires both cards to be running at x8 minimum. The specifications lists that AMD crossfire is supported but does not mention sli.

well other than the increased power requirements, your PSU must be this strong to enter, there is no danger.

There is a performance increase however it is not universal nor is it particularly stable. Games won't just automatically use both cards. The developers have to enable that kind of behavior and of course enable it correctly.

Frankly I subscribe to the school of thought that it is better to just buy the single strongest card you can rather than screw around with SLI/Crossfire setups.

Your motherboard does not support SLI, so you would only get use of the extra card for the games that support Physx and DX12 games supporting multi-GPU.

2 x monitors does not require 2 x GPU.

that motherboard doesnt support dual gfx cards. the second pci-e is for add in cards like nvme ssd's and the likes.
so yes you would have issues...
the 1070 is a perfectly decent single card for todays games. it will max out most titles at 1440p never mind 1080p.
frankly as it stands your system in its current config is a gaming beast. enjoy.

and while your cpu is overclockable running in the current board its not. but thats not to say your gonna loose much performance in real world applications. maybe a few seconds in video encoding and maybe 1-2 fps in some games.
personally i dont think its worth the outlay to switch to an oc motherboard for the performance gains you might get
fact is mate overclocking today is more about saying you can do it rather than getting any great benefits from doing it. especially for gamers.

The motherboard supports crossfire, since crossfire does not require both cards to be on X8 lanes in order to enable, the card spacing might be an issue in terms of cooling, since most ATX motherboards have an extra lane of spacing (or 2) between the primary PCI-E lanes.

Going SLI is completely out of the question with anything that isn't either a Z or an X chipset, due to the need of SLI requiring all participating cards to be on X8 lanes or more. Your second slot only runs on x4.

So a second 1070 in your case would be a bad idea.
