Need help with my set up!

[MadyTehWolfie]

So right now I'm running a 4790k and a asus z97 sabertooth mk1 mobo with a intel 750 series nvme drive. Was wondering if I could still do sli or not.

[Imakuni]

Do you already have a 980ti and a 1440p or higher display?

 

If no, then no, you can't SLI yet.

Not what I was asking at all. I was wondering if I could run two cards with my nvme not if I can run sli in general. Like will I have enough pcie lanes or no?

And that's what I'm saying, forget about it if you don't meet the above criterea.

You don't need to have a 980ti or a 1440p or higher monitor to do sli buddy stop trying to be an elitist.

Yeah, but if you don't have those, it makes 0 sense to SLI.

 

If your GPU is less than 980ti, then sell whatever you have and exchange it for a 980ti (or wait for pascal), it's a better idea than SLI. And if you have less than 1440p, adding more GPU power really isn't going to do anything; upgrade your display first, add more GPU later.

[dragoon20005]

iirc the CPU only supply the 16 lanes for GPU

 

if you install your NVME at the black PCI-E slot

 

you still can run SLi

 

the NVME will only run at PCI-E 2.0 x4 speed

Think you need to serious rethink what you just said as it shows how limited your knowledge is.

Ah thank you. I assumed this would be the case but I wanted to make sure before I moved my new mobo and os drive into my main rig.

i not sure how much the hit will be on the SSD speeds

 

since the 2.0 x4 lanes comes from the chipset and shares with the SATA ports

 

so once you have the NVME installed, you will lose 2 or 3 SATA ports

Nah, he's right. Best single card > Best SLI under same budget. SLI is just not supported well enough and scalability is not static. Every game runs differently with SLI, some games don't support it at all, and some games run worse. So, go with the best single card you can afford.

I Only use one other ssd as a storage device so its fine there. As for the speeds I think gen 2.0 has a 5gb/s speeds which is double what the nvme gets.

doing sli with 970's and 980's are still pretty good choices. Also resolution of your monitor isnt the only factor either refresh rte is also something to look at. best single card would be a titan X on water and OC's lol

yea that is the raw speeds

 

but actual speed per lanes for 2.0 is around 500MB/s bandwidth per lane per direction

 

500 x 4 lanes = 2GB/s

 

pretty fast but Gen 3 could even hit up to 4GB/s

 

so yea it half speed

That is completely ignoring the cost-effectiveness of your build. Titan's are built for content creators, not for PC gamers. But hey, some enthusiasts use that stuff. Also, yes refresh rate is important but resolution is a bigger factor when choosing a GPU. SLI 970's is still not as good as per say a 980 ti in all cases. I'd personally prefer consistent awesome performance rather than good preformance and a chance at awesome. This is because there are so many new AAA games coming out with poor or no SLI support. SLI is just not a good option right now, however that may change. With DirectX 12 we could be looking at much better SLI and multi-GPU performance, but it is all up to the game devs to implement, which at this point in time, is not something I would bet on.

Thats not bad considering my nvme says it goes at 2.2 gb/s

since you are not complaining

 

go for it

 

make sure the 2nd GPU is not blocking your SSD on the last slot

Titan X's are not made for compute only gaming. Not everyone can shell out for two 980ti's but can afford two 970's. Not saying its cost effective but some people can just dump 650 bucks at one time is all. Saying its either this or not doing it isnt something that you can blanket on everyone.

Nah it should be just fine thanks for the help.

Yes they are. 980 ti's preform the same if not better then a Titan X in games. The only advantage a Titan X has is more VRAM, ideal for rendering/compute applications. They are built for commercial applications which is why they can get away with charging double for the same gaming preformance in games. Gamers don't have a reason to buy them! I never said anything about 2 980 ti's. What I said is 1 980ti is on par or better, in most games, with 2 970's. The Dual-970's are not consistent due to varying SLI support. Therefore, overall, it's better to get the best single card you can afford vs dual lower end cards (only applicable if they are similar costs).

Alright brah unless you buy the best apparently people shouldn't do sli in your boost. PS titan X oc'd will always be faster then the 980ti.

SLI doesn't make sense anymore. The only applications I can think of are: enthusiasts who spend way to much for e-peen or swag status or because they are enthusiasts, commercial rendering/compute/etc, VR (not quite yet, couple months until that is working properly), and multi-monitor setups. It sort of makes sense to just upgrade an existing single GPU system, but personally I would just sell your current card and use the money to upgrade. I'm not saying "you need the best or just don't bother", so stop trying to twist my words because you're loosing this argument. What I am saying is, it's better to buy a single card for a certain amount versus two worse cards for the same amount.

 

ex (not real prices): It's better to spend $400 on a 980ti versus $400 on two 970's.

Give it up, OP's not listening to us.

It can make sense to SLI if you're running a Titan Black and can/want to pick up a second Titan Black on the cheap. Trying to judge other people's purchase designs, aside, I know what you mean, OP - PCIe bandwidth may be tricky to come by with two pretty high-end cards and an NVMe SSD. I would say your 4790k will run out of steam long before any bandwidth-related performance degradation. That said, you'd probably be able to find a 980 Ti new for the price of a second used Titan Black, and that would be the better solution IMO.
