Default Tri-SLI how is it? - 08-31-2014, 20:03 | posts: 7,534 | Location: Sunny Scotland

any experiences out there before i go looking at benchies.
i'm thinking if i go three cards i could go dual sli and have a dedi PhysX card for PhysX games i like.
and for non-physx games i would go full blown tri.
i do want a dedi card and this seems a good option for me.
currently i disable sli in physx games.

Doesn't it seem sort of unprofessional that the most powerful gpu setups are faulty? Why do Nvidia and AMD keep advertising unfinished products?

Elaborate. If you're expecting perfection, that doesn't happen in either software or hardware.

My GTX 780 SLI has been the most enjoyable Multi-GPU experience EVER!

That includes both AMD/ATI and Nvidia Multi-Gpu sets I've used in the past.

2 way SLI works just fine, 3 way sli and you start to have some problems in some games, with poor scaling, or no 3 way support at all. 2 way sli has very little problems, most of the time it works excellentley.

Hmm, I hear a lot of crap about SLI everyday. Guess it works then. Maybe it was just crossfire. Anyone remember the 7990? Why was that card so unpopular?

He's echoing the annoyances with SLi that you do not have to deal with in a single GPU setup.
Mainly being the need for constant driver support (half the games I play simply would not use SLi, ever). And the random occurrences of microstuttering.
There is also of lots of heat.

I've personally tried SLi once with two 8800 GT's. Dealing with driver support was horrendous, and the scaling was terrible. Worse purchase I ever made. No more SLi for me.

There is also an echo chamber here on the forums, and tech forums like it. When a person asks if I should SLi two cards or get a more expensive single card, the consensus is almost always spend more for the single better GPU. The reason sited is usually the need to driver support, lesser so the microstuttering (though that would annoy me too).

QFT, 8800gt sli was comparable to my 8800gtx sli that I has years ago, and sli is a lot more refined these days.

I wouldnt Ever go more then 2 gpus, like the guy said half the games dont have support for 2 cards let alone 3 espically older games I think?

I use to get really random issues with my Radeon 6970 crossfire setup, when i run a game my top gpu would run 100 fan speed while gpu number 2 would be in idel 25 percent this would cause number 2 to overheat thus causing me a crash!Ivtried to manually adjust speeds in Afterburner same problem, I tried using cataltst control center and same thing all over again! Heres the funny part tough when the game turns off both cards would ramp-up to 100% fan speed! Its like they made it backwards or something? Polish version of Crossfire? Sorry if anyone is polish of course.

Always better to run a single high-end card in my opinion,i ran a single gtx 580 after that and I just freakin loved it, no problems or crashes whatsoever!

My personal experience with tri and quad sli says that more than 2 way sli is more of a hazzle than a joy.

I hear you. It's hard for me to get out of the "once bitten, twice shy" mentality. I also had an AMD card a long time ago and I hated it, then loved my 6800 GT.
AMD, Gigabyte, and SLi and off my buy list. It's just a personal bias, doesn't effect what I recommend to other people (though I would warn about SLi to less tech savvy people).

I agree that if a single more more powerful GPU will do it for you that is the preferred option buying new. For some, going SLI may be a much cheaper route for a decent performance increase for less than buying a new GPU of equivalent power. However, for us graphic whores, who have to turn every setting up AND want to maintain a minimum of 60 FPS, SLI is pretty much mandatory for several titles even with a TITAN/GTX780TI. As with most things, it boils down to your own preference and budget.

some games at 1080 75fps are more demanding than others at 1440 120fps so ..
and like I've said when playing PhysX games i use dedi so currently sli has to be disabled, with another card i could keep sli enabled plus have dedi, for those games.

Well, my experience is that with such titles (Batman arkham city for instance), you either need to have a 3rd gpu purely as dedicated physx Card, or run physx on the cpu... that is if you wish to keep using sli.

I feel that at 1080p, a better option for you would be to get a 750 ti as physx Card, rather than going 3 way sli, cause 3 way sli will only give you 20% more fps at best, but increase frame latency (stutter) byt quite a bit.
