Questions about SLI?

I have a few questions (pretty noob, so bear with me):
1: In extreme gaming builds, people usually go for 4x GTX 460s. Why not go for quad 580s?
2: Which would be better, 2x 590 or 4x 580 in quad? Would there be problems?

To go with 4 x 580 in my opinion it's a non sense.
If you have one good video card who can play all the games at minimum 35+ fps it's more than enough. For the human eye 60fps and 100fps is the same.

It should matter if you have 120Hz monitor would it?

For that 580 SLI is enough. 120hz monitor is kind of pointless unless you are gaming in 3d .

^no problem mate ;) 
i am happy with a single gtx 580.But technology changes so rapidly that nothing remains 'most powerful'.for example,me and my brother decided to get the best possible single card at that time.MSi lightning xtreme edition was best.we got one for $600!but now a cheaper card(7950)beats it easily.so nothing is all time most powerful.if you are asking about multi-gpu solution then a single 7970 or gtx 680(when it comes out)is enough to run any game at 1080p.for eyefinity i would go with 7970 CF.anything above two gfx is a waste IMO.scaling is poor and it does not gives the performance of 3x or 4x of your single card.for now,if somebody wanna gift me than i would ask for 7970 CF.
it was actually fun :lol: 
if you are done than close the thread!

I'm waiting for the 680, which is rumored to come on April 22nd. I'll do 2x SLI water-cooled. Worth it?

(SLI would need price consideration...)

I have been messing with SLI for years. My first rig had 2 8800gt. I currently have a system with 8800gtx and my main system with 2 gtx470. I use my SLI to run 3 1920x1080 monitors for a surrond resolution of 5760x1080. Its fun but not very practical and it is often a pain in the butt. Its hard to recomend SLI to anyone other than a hard core enthusiast.

4 gtx580s would be neat, but not practical. 4 cards would cost close to $2000 US. The PSU they would need would be like 1400watt and 120amp, or maybe a dual PSU. Liquid cooling would be the only real way to keep these cool other than a case that had a house style window fan for a side panel. While on the topic of cases 4 cards would need a fancy case with 8 expansion slots.

If you had all that in place what whould you be able to do with all that power. One 580 will give you acceptable frames in most any game, 2 would give you good frames.
I guess the common man could use all that power for brute force password breaking.
Or maybe folding at home.

sweet pic.
A few months ago i came across an 8800gt that was match for my 2 older ones. So i tried to 3 way SLI them to see what would happen. Unfortantily the driver will not let you enable 3 8800gt, intead it SLIs the first 2 and then sets the 3rd for physics. I found a crack and a registry tweak that let me enable it but it did not run very well. The 3 8800gt ran only 10% fast than 2 and the driver often crashed. I even tried to make a custom bridge by cutting a 3 way in half so that it only had 3 connectors rather than 6. That did not seem to help at all. It seemed to run the same with or with out a bridge.

Complete waste of money. In fact, if you added a third GTX 580 it would just be sitting there causing noise and heat and not really contributing to any rendering whatsoever, so for a fourth to be there... :heink: 

In fact last night when I was busy gaming away with my two GTX 580s I'm pretty sure that I could have easily fried an egg on the back of my case it was so hot. Had to set the fans to run faster and temperatures came down by 15 degrees celcius or so.

Also, not many games will support anything more than 3-way SLI. It's honestly just an all-round waste of money. People that do it are just :pt1cable:

I got a feeling that SLi GTX 660-Ti will be strong enough and equal to stronger than SLi GTX 580's.
I think I need to move up from these x8/x8 boards to some x16/x16 boards but reports say that if you already have x8/x8 then just keep it.
not worth the money to jump up to x16's..


The GTX 580 is the fastest single GPU card Nvidia has got to offer as it stands now. The GTX 590 being the fastest single DUAL GPU card.

Nvidia would never release a GTX 660Ti that performs at the same level as their current flagship card, the 660Ti will be aimed to be competing with the likes of the 7870 etc.

The GTX 680 will compete directly with the 7970 and will succeed the GTX 580 and the GTX 590.

An overclocked GTX 660Ti will perform as fast as or faster than a stock GTX 570 no doubt, that's if the past is anything to go by.

I thought that at first too but the jump in the GTX 6 series is suppose to be more than the jumps in the past.
and the GTX 680 the first to be released was actually suppose to be the GTX 660-Ti or GTX 670.
when nVidia realized how the HD 7 series underperformed in their eyes, the lowered the the chip to match the HD 7970 performance.
so basically nVidia is holding back and will charge some ridiculously insane high prices when they do decide
to release the 'big boy' into the fold.


I believe that both companies have cards that are hundreds of times faster than the ones they've given us.

Take Crysis for example. That game was designed on Beta hardware. And even now it still spanks even the top end cards. So what the hell did they develop it on to have it running at 60+ frames in 2007?!?!?

That's FIVE years ago.

It's just like the gas companies. They've got the designs for cars that run without gas and when the gas runs out they will control those too.

Conspiracies all around us!

I has an awesome P55 EVGA SLi E652 pushing an i5-760 @ 3.52GHz, I loved that set-up.
ran x8/x8 in dual and that was cool but still ran x8 in single.
not cool.. :pfff: 


You were running it in the top slot?

I made the same mistake. Had it running at 8x/16x .... :non: 

You have to read under the PCIe slots... they specify what speed the slot operates at. Why on earth they put an 8x slot at the top I don't know. Maybe they just assume everyone will be running 3-way setups.

Despite what I've read about 16x having no tangible benefits over 8x in terms of performance, I would also be highly p***** off!

it took 3 GTX 580's to run this in real-time, 2 in SLi and the third was PhysX in the first set-up.
the seconds set-up was a single Kepler GPU.
this is my reasoning for thinking that the jump will be more than in the past.

And this is also just depressing... I put way too much money into my computer as it is and now with the release of this card things will change. I reckon it'll be priced around £700 or $1000 as well?

Only time will tell.

Some interesting results here today and hopefully we've helped clear some of the confusion up around the x8 / x8 vs x16 / x16 argument on the P67 / Z68 platform.

So what you're saying is that Price per performance 8x and 8x will be best?

I haven't heard of many people using SLI 590s, it's not such a common setup.

OMG 680 in SLI will be overkill. My 580s will do me just fine for the next year or two :sol:

wrong, where are you getting this *** from? can someone else with a 120hz monitor please explain to these people that 120hz in 2d is a 1000x times better than 60hz in 2d.

Heres a simple trick, i move my mouse accross my 60hz monitor theres a trail (2ms response time asus its not old its fast), i move my mouse across my 120hz monitor and theres no trail. When i played games in 60hz in 2d there was always a sort of motionblur/lag/whatever it was , no matter what i did to the settings. now that i have a 120hz monitor, there none of that

Guys, 120HZ will still be better. It comes down to your FPS. If your run 60 FPS on 60HZ and 60 FPS on 120, it'll look the same. Play 120 FPS then you'll see it. 120 HZ is the best for both setups, 2D and 3D.

Lol, this thread is about SLI. Youll hit that easily.

One thing out of curiosity, will 2x 590 perform as well as 4x 580 in sli? (in fps and bench). 590s are slower than 580s, so I'm expecting 580s to win by 5-10%?

And let's be realistic, you won't score 120+ fps on a newer game unless it's a 2D game.

OR and older game (except Crysis, which I was getting between 50-75 fps last night with my GTX 580s)
