Need Help!! 1 TitanXp or 2 1080 Ti

[CGameDev]

I need some serious input. I was considering changing upgrading my graphics card and I need some feedback. I know computex is basically over and AMD have their Vega GPU coming, but am not sure of the price when it launch, so i am working with what i know. 

So guys, based on experience which combination is  better price per performance, keep in mind this is not strictly a gaming system, its mostly for Game dev using Unity 5 and Unreal Engine 4. I already have a i7 6700K OC @ 4700Mhz stable for several months with 32Gb ram. So I am open for any logical suggestion that do not include unnecessary spending.

2 1080tis

1080Ti is 95% of a Titan Xp. Why it lost 5%? Well, 1% is on performance difference and 4% because it does not carry "titan" in its name.    Titan X Pascal got slapped twice

 

So, pick 2 1080Ti unless you want to enter the Titan master race

The sensible choice would be two 1080Ti´s... As much as that can be called sensible

The 2 1080 ti's will give you much more vram to play around with so id go with that.

VRAM does not stack in SLi tho.

but as for individual cards it may not stack but processes can be allotted to one gpu or the other

Well i made the mistake of getting the Maxwell TitanX when it came out and when the 980Ti came out i was pissed based on the performance per $

Lesson: Titan cards are for the rich who cares about name more than being sensible.

Well I know that much but I think the extra card will help when I am rendering large scenes especially when they are full of assets. Is my theory correct?

Should do. Never really done anything massive with game dev. But it should work out. 

 

Two cards also looks better than one

Honestly youll love the 1080ti. Like mentioned earlier the titans are basically over priced lol

the fuck are you talking about? 1080 tis have 11 gigs of vram

yes? and he has 2 of them which gives him a theoretical 22 gigs of vram?

lmfao thats not how it works

you can allot tasks to one card or another. I know sli doesn't combine the amount into one but if he properly manages what tasks go to what gpu's he can have a max theoretical of 22 gigs.

im sorry but... no. that requires virtualization or very niche programs

did he say he wouldnt? no. Dont make assumptions, plenty of people dev in vms. Seeing from your recent forum posts youve been taking hot L's all day. Please do not misinform people. That is all.

ffs mate he has a 6700. no one would create a vm with that cpu. 
and wtf are you talking about?

As someone who had this exact debate about the 780 Ti vs 2x 770, get the single card. I went with the SLI option and regretted it big time. 

 

1. Not all games support SLI, so a decent portion of the time you end up with one slower card. 

2. Unless you plan on watercooling both cards the top card in the stack is going to be throttling in long game sessions, as the heat from the backplate of the bottom card gets pulled into its cooler. Games don't like it when SLI cards run at different speeds, and often crash when the discrepancy gets too far apart - you will see this as driver has stopped working errors. If the top card gets TOO hot, the entire OS can crash because it's the primary display adapter. Took me weeks of tinkering before I figured out what was causing this issue. I was running in an Air 540 case, so more airflow isn't enough to solve this.

 

So save some money and frustration and just go with a single faster card.

If we are talking about FE card, then I suppose it is the case.

 

But this just simply does not happen in any aftermarket 1080tis as long as adequate airflow is achieved with case fans.

I don't even think you need a BM as you can use the cards separately if I'm not mistaken. (I swear if you reply "you are mistaken" without any proof. 

@theminnesotanmanjust wanna say I also agree with you

I have an Asus strix 1080 Ti, and the backplate sits at or around 80c under load. That's with 2 140mm airflow fans in the front of the case blowing across it. That means the top card is going to be pulling in 80c air from this heat source that's about 1cm away, while the while the bottom one will be pulling in whatever the ambient is. Custom cards in the Ti line probably actually make the problem worse as they are often 2.5 slot designs with even less space between the cards. Remember that I was using a pair of Asus AIB 770s and an Air 540 (the original high airflow case) and the problem was pretty bad. 

 

Bottom line is that you *might* not have the issue depending on your case, but if you do you are kinda hosed, while a single faster card will *never* have it. Given he is upgrading an existing rig, chances are that his case isn't a super high airflow design. Add to that the growing list of modern titles that don't even support SLI, and this isn't rocket science.

 

Speaking from personal experience with the 1080 Ti, unless you are running 4k the thing is going to be fast enough to last a couple of years with games on or near max settings anyway. At 1440p I pretty much never drop under 100fps with my 4770k @ 4.5ghz. Get a single 1080 ti and use the money you save to get a big NVMe drive to run your games from or something.
