Does anyone still run 3gb 580sli ?

The most I got out of a 480 was 7000 points, around the same as a 7950 running it at 960mhz under water. IIRC the stock 580 scored around 6000 points making both it and the 7970 far faster than a single 580.

The 750ti runs both the 480 and stock 580 close so even running two they will not come anywhere close to the 780.

Those numbers I pulled are from 3Dmark's website so are irrefutable. Going by those numbers (because SLI scales perfectly in 3Dmark 11) it would take three 580s scaling almost perfectly to get close to the 780.

Sorry man in this instance you are clearly wrong. I still own a GTX 480 Lightning which is every bit as good as any 580 and compared to any modern card it's ancient history.

I really don't understand why you are giving the OP false hope.

It's saturday night and i have gaming to get on with but in closing i will say this, you are wrong. The 580 sli will compete with a single 780 in most circumstances. Dont take my word for it though, i am sure someone else has made the upgrade from 580 sli to 780 and can share their findings.

'not an issue' does not contain any fact whatsoever. Case in point people told me they didn't have any issues with crossfire before it was exposed.

Got any benchmark results?

It's kinda hard given I'm on my phone but a 3Dmark 11 run will do.

580 sli 11057.
780 16482

I rest my case.

I really doubt that a single stock 780 gets 16k in 3dmark 11. A friend of mine ran it with a stock 4770k and only got 8000ish.

Where you using the same CPU for both sets of results?

Oops Im thinking of firestrike! Come to think of it that surely is the better comparison for vram usage.

A gtx580 is similar in performance to a radeon 7950, maybe a hair slower. That being the case I'd bet that in SLI in a lot of cases they could beat the gtx780.

If I had 6gb 7970s they would be much more future proof, and four of them would probably be good for 4k even.

I dont upgrade every gen, but next time ill get the higher vram cards for more longevity.

Not quite true. The 7950 was a good 15-20% faster than the 580 when it launched and that was on early drivers. I still own a GTX 480 Lightning that I have been benching lately and it clocks to around 890mhz on the standard air cooler. Even at that it barely makes 6500 points in 3dmark 11. A stock 780 will do 12,000 with a decent CPU behind it.

Try to remember, 3dmark 11 is pretty much going to be a best case scenario for 580 SLI. It works properly and it scales properly. Sadly since launch it has been updated and thus that throws the scores out a little (and changes due to drivers and so on) but I am still going to hold firm here.

Apparently Bioshock Infinite holds up pretty well for triple SLI. At least that's what I was told when I bought my third Titan Black. Thankfully since then I have decided not to go tri SLI as I managed to see sense right at the last minute, but just take a look at how three 580s do when put against a 780ti.

So I'm sorry I'm going to stand my ground here. You would need three 580s to topple a 780 and then you would have to basically plug and pray for driver support. Two are simply no match.

Edit. I also want to add that the guy here who says he upgraded from 580 SLI and compared it to a 780 would have been doing so on very mature Fermi drivers and very early 780 drivers. Things change as a technology matures.

I'm sure in actual games the sli setup would still hold their own. 3D mark 11 is going to work better on newer tech. Nonetheless i'd like to see some benchmarks on the latest drivers with both setups.

I linked you to an actual game and three 580s were no match for a 780ti.

I know the TI is faster than the basic 780 but it wins quite conclusively in game.

I know I shouldn't rely on 3dmark 11 but it usually gives quite an accurate idea of GPU hierarchy.

My 480 Lightning is very similar to a 580 given it runs at much faster clocks. But even the 580 Classified which ran obscene clocks came nowhere even close to the 7970 I bought at launch, and that was long before the 7970 drivers matured. It also doesn't have the throttle the 580 has.

I can't score half of what a 780 does with my Lightning, so even if it was 100% scaling it still wouldn't topple a 780 even if I added in a second.

And then there's driver support, game support, SLI support and god knows what else. I would lay a bet that Nvidia stopped supporting Fermi ages ago. It only took them three months after Fermi's launch to stop all support for the 200 series.

And lest we forget power consumption !! two top end Fermis guzzling down juice. Even the 500 series were still greedy.

Feel free to stand your ground man, you are wrong. The performance difference between sli 580 and a single 780 is marginal. I compared my 580 sli setup to the 780 ghz edition that replaced it and there was next to nothing between them and the ghz edition is a fair bit faster than a standard 780. If the performance difference was as wide as you suggest, I would probably not have added another 780. If the performance is as you suggest, you should have no problems proving it. So far, you have been proved wrong all the way through this thread.

Video posted June 2014. Have you done any testing since then?
 
As posted above my cards are gone 18 months so obviously not. The link you posted is irrelevant as your entire point up to now has relied on the 3dmark score you posted. The 580 did not scale well on 3 cards as i looked into it at the time and decided it wasn't worth it. Additionally, there is no indication on that video of gpu usage across the 3 cards. Also, we are talking about the 780 not the faster ti version. Nor are we talking about power consumption.

It's irrelevant yet it shows a single 780ti walking all over three 580s in a game that's supposed to support three GPUs quite well.

http://www.guru3d.com/articles_pages/geforce_gtx_980_sli_review,15.html

There is some scores from the same game running three 980s, so as I said the game scales perfectly well on tri sli. It's right about what you would expect, actually.

And yet the 580s don't come anywhere close.

Any way whatever. Done with it now given you're just saying the same thing whilst providing no proof of what you say.
 
I remember threads appearing all the time on this forum about whether to go 580SLI or 780. It basically went down to choosing between lower heat, less power, and less potential for driver issues. In terms of raw grunt of the two, they traded - the question over which setup was faster was rarely in question due to them being almost identical.

Unfortunately, we have a certain person who's always right beating his chest because tri sli 580s isn't as quick as a 780ti as such he's right over 580sli trading with a 780.:rolleyes:
