The big 970 SLI dilemma

you had better get in there quick and buy one as I am sure Gibbo said these were going back up in price next week..

If they go back up the 970's will be better value for money again with little to no performance gain.

Thats fine. If they do go back up, I'll find something else. I was even planning on buying a new PSU to power it too. I can't order until I recieve a refund for the 970's which is going to take at least a week.

Theres also the 290X crossfire option also.

I have a swift, I've run it on 7970/7990 trifire, a single 980, then 980 SLI.

Single 980 will net you 50-60FPS in most games, excepting the outliers, if you want to actually see an advantage from 144hz you need two.

To be honest I'd keep the 970sli.

GSync masks the lower FPS rates but why have a 144hz monitor and have it spend most of it's life sub 60 fps.

Some games cap to 60fps anyway (e.g. Wolfenstein New Order, Ryse) and for them you are as well with a single card really.
 
Hi guys, Ive got 2 MSI 970s in SLI and run a 2560x1440 overclocked monitor. I have not noticed any stuttering or anything like this at all on games running above the 3.5 zone.

Currently playing Elite Dangerous at 110hz maxed out and at 3905mhz on VRAM. Nothing not a moments stutter. And i play Titanfall again 110hz/fps and its butter.

Is this effecting all cards?

I had the 980 for a day then sold it as it was not giving me the fps i wanted at this resolution. I would prefer a single card for reasons we all know but for me i think im sticking.

Its like Gibbo said the 980 suffers from stuttering in certain circumstances its not just down to the vram issue. Driver versions and users PC' hardware is also the cause.

If you think about it. The 970 came out, what last September. Are you telling me out of all the games out since then only the ones out since January are causing the stuttering on the 970 ? Why was there not a big furore about it before. The VRAM issue has existed since the card was released. There is still no 970's yet in b grade yet there has been a 290x for £229 sat there unwanted for as long as I can remember.

Sorry getting into VRAM territory again. Bad me bad me.

I reckon that 290X is still there because it's the SAME price as the regular priced one... so would I buy it at the same price but with a 90 day warranty? Errr, let me think... ;)

EDIT: Actually, I may be wrong on that... but it certainly APPEARS like it is. There's one at £281 which is on pre-order. The regular £229 one looks identical though. Maybe that's confusing people, as I think the only difference I can SEE is the box. Why IS one £50 more actually??

I'm thinking of returning my 970's in exchange for a single 980 and a credit note for the outstanding balance. I like the Windforce cooler, so it's looking like a Gigabyte GeForce GTX 980 G1 Gaming...

The big dilemma for me, is should I do it!

I can't answer your main question, but I wouldn't get that particular card if you are even possibly going to SLI in the future. Rather, get a card with a reference cooler.
 
I had the very same discussion with myself and I was actually able to do something about it.
Having one PC with 970 SLi and another 970 3 way SLi, I was thinking of going 1x GTX 980 in one PC and 2x GTX 980 in the other PC. I knew very well that selling 5 GTX 970 would not cover the costs of 3 new GTX 980's...but I was kinda accepting it albeit unwillingly.

Luckily my buddy came to the rescue ! We talked about it and he said, "hey why don't I come by with my 2x GTX 980 and my 4K screen and we can check if it really is an issue".
So last evening we ended up swapping testing 1x GTX 980 vs 2x GTX 970 and 2x GTX 980's vs 3x GTX 970 and 2x GTX 980 vs 2x GTX 970 all in 4K.
Aaaaand halleluja I was happy with did that.... it saved me hundreds of quids.

Fact was that we played every new AAA title in 4K at max details and minimum 8xAA in all titles. We were excited to see if the Vram "issue" on the 970 would cripple it.
We did all the first testing with 1-2-3 GTX 970. With 1x 970 card FPS were low and at these quality settings games weren't really playable.

2x GTX 970 improved things a lot - we loaded the games with 8xAA and we experienced stutter every now and then and the VRam usage was 3.5GB+ and texture popping was random. We backed down to 4xAA and things lightened up. Still not stutter free and occasional hickups but we didn't see texture popping. Then we backed down to 2xAA (still looking sweet in 4K) and now things rang smooth as silk and we didn't experience stuttering at all.

Now to 3x GTX 970 - fired up the same games and Dying Light the "problem child" for the 970 Vram problem we tried first. Set it to 8xAA and we still had massive stutter all over and texture popping like with 2x 970. We downed AA to 4x and now things got weird. Absolutely smooth gameplay eventhough the Vram was hitting 3.8GB !!!. Maybe that extra GPU really made a difference now backing up the Vram ! We didn't see that coming.
The same story we repeated in the other games BF4, BioShock Infinite, COD Ghost/Advanced Warfare etc. Gaming in 4K with 3x 970 was a breeze with max 4xAA.
All in all we were sure we had seen the "3.5GB+ 0.5GB" problem in the games.

Now we moved to the GTX 980. 4K same setting Vram usage 3.9~4.1GB with 8xAA. But heavy stutter stutter and low FPS. One card just can handle it. Backed down all the way to 2xAA before with got FPS though would touch the likes of 30FPS and Vram usage between 3.4~3.5GBVram

Moving to 2x GTX 980 we expected the 980's to show their REAL 4GB Vram available. Fired up Dying Light set to max and 8xAA. First minute was smooth and we were so confident that this was how real 4GB vram would run the game... but them BAAAAM... suddenly the memory usage showing 3.8 went to 4.1GB and we were back to texture popping and choppy gameplay just like the 2/3x GTX 970's.
We could not believe it so we restarted the PC and game - with that that 3 times in a row, but every time the choppiness and texturepopping returned. Even 4Gigs wasn't going to cut it to run 4K at 8xAA. We backed down to 4xAA and here we started get get smooth gameplay again, only once in a while when a lot on the screen happened the FPS would back down in the low 30FPS - not surprisingly the 3x 970 delivered much better gameplay experience and FPS smoothness at these same settings.
After that we continued to tests in all the other games. We were surprised to see that all the games behaved in the same manner 8xAA at 4K was too much for even two 2x GTX 980's to handle. Vram usage was oversaturated causing stuttering etc. Backing down to 4xAA things got a lot better and games played smoothly albeit with a lower average FPS than 3x 970's.

So all in all. We played through all the games and I must admit that the 3.5GB+ 0.5GB vram issue was only "evident" when the 980 REAL 4GB card had the same problems !.
I'm really not that sure that the 970 is a crippled card at all, because when the 970 had problems so had the 980's.

Right now I am actually very happy I didn't sell my 5x 970's but decided to keep them. I'm thankfull for the fact that I for myself could test things out before throwing hundres of £ out of the window for nothing - so a hughe thank you to my buddy Jess :D I've seen it with my own eyes that "upgrading" from 970 "3.5GB+0.5GB" to 980 4GB is useless.
When 8GB versions of 970's get here I'll purchase those also eventhoug they may be "7GB+ 1GB" or so.

I hope you can use my answer to something. :)

It is good to see someone do some real testing.:)
 
Thats why I put it in " " ;) Is a 4gb card any better then in those terms ? I think no.



I have had a 290 and it was a good card surprised me but the heat, oh the heat, that did it for me. I've tried a 980 so I wouldnt go there so there is no where I want to go at the moment.

If there was plenty of 8gb choice then I would take advantage of the refund and not necessarily for the vram issue reason but there isnt. So stick not twist.

Are you gaming in a 2 by 2 room or something as oh the heat the heat is overstating things. I have a 290pcs+ and it runs at 65oc load and barely dents my room temp and certainly does not change other temp inside my case. My mate has 2 x 290x pcs+ and still no problems. Sure they give off more heat but Fermi top end was similar and other top end cards of the last 4-5 years were not so far behind. It seems since Nv went to kepler it's all about heat and power usage lol.

It does not make much difference to my room temps leaving all 4 of my 290Xs chugging away 24/7.

In this cold weather my biggest complaint about the 290Xs is they don't produce enough heat lol.:D

Lol lucky for me my Pc is backed up by loads of other electricals in my living room. It's still not enough when the temps outside are close to 0. The bottom line is unless you are playing in a shoe box heat is most likely not going to be a problem as sweating goes.

Awesome post, thanks for that.

I've said all along that I am happy with the SLI performance, it's the resale value that's my main concern now.
 
I am concerned my resale value primarily also. I don't think the future proof argument holds with 980s as RAM is going to be an issue with those too. Also the price difference is just categorically not worth it. Going from two 970 to one 980 is a catastrophic performance drop that would make a lot of games unplayable.

I paid 263 each for my 970 windforce OC on Black Friday. I also sold the games code for 25 each. Total cost 475 for the two cards. The question is what will happen to resale value? 10% less? 20%? At 10% drop its not worth it. Would cost 20-25 quid to get the pair of them back to OCUK!

I am confident that they will hold up at 1440p with 2x AA and that above this they run out of horsepower anyway. But because of the resale I'm still on the fence :(
 
Another thought on resale. Regardless of the 970 issues, when the next generation come in you can probably expect this generation to drop across the board by perhaps 20%. That is is going to hit 980 owners harder than 970 owners as the c15% performance difference isn't going to be worth as much as it is today when there's a new generation of cards out offering 30-40% more performance than the last.

I think that as long as you're planning to keep the setup for a good period of time ie 12m+ this hit from this is going to be relatively negligible?

If however you want to upgrade soon the best thing to do is probably take the refund, buy a cheap 290 from MM for a few months and see what the next feb looks like...
 
Cracking post by Gripen90,i am erring towards keeping my sli 970's,its just the niggling feeling of being,well,lets say misinformed about what I was getting for my hard earned(at 60 years old,and still grafting,believe me I mean hard).
Still on the fence if truth be told,But I must say WELL DONE to OCUK,i would recommend them to anyone over any other etailer.
 
Do we think a 6g or 8g is comming soon? Cause im happy with my 970s. But im tempted to refund and wait a month or two for larger memory versions.
