- GTX 970 SLI vs R9 290 CROSSFIRE - Tech Support
Got a question, has anyone had any good results from using NVidia Hybrid SLI?
Here is my setup,
Asus Fforce 750a chipset with onboard GPU for hybrid use only.
NVidia GTX 285 x 2 SLI with water cooling.
Now I know those two GPU's eat lots of juice and I'd like to find a way to turn them off during web browsing / common PC stuff and only use them when I'm gaming. I was originally interested in using Hybrid SLI so that I could use the system this way. Has anyone been successful in setting this up on Windows 7 Ultimate x64?

There a few things that need to be cleaned up in the description if it's to remain a sticky.You need to change the wording of the description of Xfire, you make it sound like ATi copied nV when if anything it's nV who copied ATi and Metabyte's methods of doing multi-card graphics. nV's SLi bears no resemblance to 3Dfx's SLI in anything other than name. And SLi didn't come first in the rebirth, that was Alienware's failed ALX and XGI's volari V8 Duo. And ATi was doing their SIMFusion thing the whole time with Evans & Sutherland.
Also you need to split the solutions up, since your first example of the same cards applies to SLi but not Xfire. So it should be clearly defined which one you're talking about, you examples lets someone guess, but it needs to be explicit.
And in the memory example following it, you talk about memory and then talk about speeds. The 7800GTX is a bad example for memroy since there is athat large difference. But when mentioning memory and talking about size you should mention the size being affected and that they will disable the added memory. You're sort of mixing your ideas here. Then right after that you say you can mix/mathc brands but make sure they have the same memroy and clocks, yet right before that you imply/state they can have different memory/clocks.
For an Xfire section you should add that while the cards need to be the same underlying architecture, they can have different numbers of shaders or pipelines and still work together, like an X1900GT + X1900CF combination.
Also when talking about multi GPU benefits, rememebr to mention that one of the areas of greatest impact is also in the minimum fps, where it will usually increase min fps and smooth out dips into the lower numbers. It's an important factor that's usually missed in the discussion and is the area that would be most noticeable to people not looking simply to push large resolutions or high settings.
And when talking about does it always improve performance, you should also mention that sometimes it actually hurts performance when using the additional card.
When talking about the memory doubling myth you may wish to expand on how the memory is used and why it doesn't 'double the memory' when in Crossfire/SLi mode.
When talking about 2 midrange beating 1 high end, the thing to rememebr is that there are exception to that, like 2 GF7800GTs beating 1 GF7800GTX-512 for less money, or 2 GF8800GTS beating a single GTX or Ultra for the same money, but it depends on the situation, because there's no clear cut rule for that.
I'd get rid of the 'which is better' comment, you could discuss that with intelligent people night and day and never get and answer, and posting to any one benchmark doesn't solve that question either. So I'd pretty much avoid it unless you take the time to explore it further than a link to a single group of tests.
Also I'd avoid posting a list of cards, unless you can keep it up to date and include all the sub cards, better to just link to AMD & nV's list thus the onus is on them and not you.
BTW, what the Crossfire/SLi RAMs sections? Sounds like you're talking about the 'certified' parts. But the way its written sounds like VRAM.
If you're mentioning 'Crossfire/SLi editions' etc. you might want to mention that for AMD the boxes stamped 'Crossfire Edition' come with the ribbon connectors required to run cards in Xfire.
There's also a few spelling mistakes, but I can clean those up directly if you want.
LOL i though it is crossfire the fps game problems on a SLI Graphic card

A crossfire question.What about the cards that DON'T have the additional power connector, like the 5670, 6670 etc. whose TDP is just under PCI-E's 75 Watt power limit. Won't they have power problems ?
Or does it work in this way, that each PCI-E slot has it's own 75 Watt limit ?
You can X-fire two sub 75 W GPU cards together, as long as they are the SAME card. No, they won't because the PCI port will supply enough power to each individual card. Each slot its own 75W limit for the GPU card it has, regardless of X-fire.

thanks Maziar for this thread.
I am in a midst of building a news system based on 2500K and AsRock Fatality Pr P67.
But I am stuck with choosing my GPU setup
1) 2 x HD 6950. this options seems to be the best in terms of cost vs performance. My only concern is I have never had SLI/CF setups and I am a bit concerned. From what I have read, the performance of 6950 CF is superb but all the talk about some games not taking advantage of the CF setup is worrying for me. Will i also need to invest in better cooling if I go with a CF setup? how about overclocking? is OCing a CF card more complicated than a single card?
also when choosing my 6950 cards, do I just go with a basic stock model or is it worth going for the more expensive cards like Asus or HIS with their factory OC and superior cooling?
2) A single GTX 580 or a single HD 6970. This option seems OK too since it allows me to add another GTX 580 later if need be.
3) A single HD 6990. I was about to go with this option but seeing how the card is being said to be noisy and hot and since there are no real improved mods in the market, I will probably not go with this option.

Hello - been reading through the FAQ, quite informative. I noticed people post a lot of questions on their setups in this thread so I thought I'd throw out a line -
my setup - i5-750, asus p7p55d-e pro, 8gb RAM,
current card is gigabyte SOC 470
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
My particular card (which I'd argue is the best 470) has become quite rare and would probably be quite expensive even still.
So my question is, at this point would it be worth adding an additional 470? It seems I could get one on ebay for $100-$150. I understand that it doesn't have to be the same model - so what would be the closest match? my 470s stock speeds exceed all the others - so I'd have to lower them to match the weaker one, is this correct?
Please help me make an informed decision

No,each card will operate at their default speed(sorry for the late reply)

No,it's not possibleThanks for ur reply mate !
So i already have a nvidia quadro 2000 ! I actualme in my lidly building a new Pc ! First time in my life
Not very wise !Im stuck about motherboard
I have a I7 2600K CPU !I dont know what motherboard i could get ! I have been looking at some !
Like Asus p867 Ws revolution Or Like Msi big bang Marshall !
Im building it for multi purpose ! But the main purpose is 3d softwares and video editing !
And i want to install 2 more gpu. Like 1 Quadro 2000, and for gaming double nvidia sli ! Or double ati ! I dont know if its possible like switching between of cards ! Like when i work on 3d applications use quadro and for another things use another double card !
I hope this is not a ridicuolus question
So what mother board should i get ? And can i put videocards like i drivelled above
And i really would appreciate for ur other recommendations..
Like Cpu Cooler, SSD, PSU etc...
Thanks

Thanx so much for the Informative article Maziar
Cleared up the few things I wasn't sure of and I know I'll be linking this for others who have questions about SLI and CrossFire. Excellent Effort. Well Done.
Just a quick question if I may:
Currently , what would be the best (minimum) Budget Radeon Card to buy right now ... for the potential to use CrossFire down the track.
That is, I want to just buy a cheap GPU for now to get me by and then later upgrade the Mobo to Crossfire compatible and then buy a second matching GPU to run alongside the first.
I'd prefer it to be 128bit , DX 11 , OpenGL 4.0 etc (a recent card) ... but want to keep the cost down. preferably under $80. SO I know that a while ago 4550 or 5550 were popular ones to use (from memory) ... I'd prefer a 6*** series tho.
(FOund a 6770 @ $77 but it sold out instantly before I could buy one
... now I can't find that card anywhere under $100 .. even $120 , bummer)
Would you go anything lower than that? and Is there certain models that yield better performance results than others?
Cheers.

Ok hears my question i have spent 2 days reading through this forum and still am not quite sure which is better so i will ask you guys. Which would be better
2X NVIDIA GeForce GTX 570 1.2GB 16X PCIe Video Card (EVGA Superclocked)
or
1-NVIDIA GeForce GTX 580 3GB 16X PCIe Video Card
Any help would be great

I plan on upgrading to two gtx 580s in SLI and don't want to get rid of my three monitor setup.So I have another related question to anyone who uses nvidia surround or sli with multiple monitors. Right now with a custom driver (Its not really a full sli setup) each monitor I have is independent (Which means I can drag a window to one monitor and maximize it only on that monitor and do likewise to all other monitors.) What will this experience be like with sli and three monitors? Also when I game I only like to play across three monitors with certain games. A lot of FPS games I don't like to play with that high of a resolution and fov. With surround and sli enabled can I play a game on one screen without disabling sli or the other two monitors? (Maybe just change the resolution in the game and it goes to only one display?). Thanks in advanced. Still waiting on my card in the mail.
P.S. I asked my boss these things and he told me he doesn't do sli, and therefore didn't know too much about it, but that I was too picky when it came to getting things to work on computers

I currently have a 6870 Black Edition in my desktop. Plan to buy another as soon as the price drops, again. Right now after MIR it's 210 (after tax) on newegg. I've looked at tons of reviews and one thing I noticed, that wasn't mentioned in the article is a significant benefit of having two gpu's.
I don't have a long history in graphics cards, so I can't tell if this is a recently accomplished deal with scaling, but from the reviews I've read the 6870's in crossfire have a higher minimum of FPS against the higher-end gfx cards (GTX 580 OC's and 5970 OC).
I'd take a higher minimum FPS over an extra 30FPS at something that is already 130 FPS (which is hardly noticeable). I haven't done any research into other CF/SLI set ups, but if it is a reoccurring aspect of Multi-gpu set ups, I'd definitely add in that with a SLI/CF set up, higher minimum FPS is an advantage. Higher minimum is pretty big in my opinion and I didn't notice it being mentioned at all.
The review I based this view off of is from here:
http://www.hardwareheaven.com/reviews/1062/pg13/nvidia-...
Just a thought, not trying to create a significant debate.

Can I add a second 580 to the 4x pcie to achieve sli? I didn't think 16x/4x was possible. When my mobo arrives, Gigabyte ga-z68-d3-b3, I will be putting a gtx580 in the 16x pcie, and am curious if I can sli if I buy another card next year.Is SLI an option for a motherboard that only has Crossfire support (which I am pretty certain is the case for this board)?

So the software prohibits 16/4 sli. Has anyone tried it anyway?There are many hacked NV drivers out there to do SLI on AMD chipsets as such(other non sli systems), but not promise they will work in this case.
