hi i sold my 5870 cf setup to get 2 gtx470 sli,all games are slower except metro and mafia2/i ra furmark and got a score of 38000 which is worst compared to the 50000 i used to get with my 5870,i got a 25000 score in 3dmark06 with a single gtx470 oc to gtx480 speeds but when i ran the 2xgtx in 3dmark i only got 27000,ive renstalled the latest drivers twice now and sli is enabled,also whe i ran furmark it said in the score that there is only 1 gpu active is this right,it always said 2 are active when i ran my old 5870 cf,are there any settings i should know about in nivida control panel that might be causing these to run slow
 
Something to check:

Download MSI afterburner (if you don't have it already), and run a benchmark of some kind. Not 3dmark06 though, as that is massively CPU-limited.

When the benchmark is finished, check the GPU usage history, and check whether both GPUs are actually being used (both GPUs should be close to 100% load, or at least, should have a similar load).


Also: What motherboard are you using? Did you properly clear out all old ATI drivers before you installed the nvidia ones (i.e. did you run driver sweeper?).

What I mean is to check the actual activity of the GPUs. In real-time, while the benchmarks are running. What percentage of the capacity of GPU1 is being used, and what percentage of the capacity of GPU2 is being used. You can see this from afterburner, in the "hardware monitor" window. It plots a graph of GPU usage over time.

I understand that SLI is enabled, and that GPU-z recognises it, and that's a first step. But it's important to verify that both GPUs are actually being placed under (equal) load.

To those saying that 5870s beat out GTX470s... I'm not sure that's true, but I suspect that they are close. But a 5870 CF setup scoring 50,000 in furmark and a GTX470 SLI setup scoring only 38,000 is not consistent with this. It indicates a real issue with SLI being enabled.

And again - it would help to know the motherboard, and whether you ran driver sweeper before installing the nvidia drivers.
 
i checked msi,it says there at 95% load,i also ran furmark again and got 42000 still not 50000 though,i installed the drivers twice and ran driver sweeper each time and removed all the ati drivers,i have asus pt6 delux,any idea whats wrong here
 
3DMark06 is not reliable nowadays...so I would say just ignore that.

And I agree with Duff-man about monitoring GPU usage/activity in real time. You can use MSI Afterburner to display those details on screen. Go Settings->Monitoring->click the GPU usage for the as in OSD->check the box for Show in On-screen Display.

Some screenshots of the MSI Afterburner graphs (i.e. GPU usage) might actually make it easier to determine what the problem is.

the days still young, trolls sleep till mid-morning from being up till 3am arguing on ze interntz :p

i think 470sli will only do well over 5870CF in the odd game where the ATI's dont scale well

Nvidia perform better in some titles and worse in others, this includes benchmarks. Neither of them dominate in everything. If you are worried something isn't right compare your results with a similar setup on ORB or on the relevent benchmarking forum.
 
i checked out a lot of benchmarks and a gtx470 sli overclocked to gtx480 speed is atleast on par with a 5870 cf sometimes beating it,a gtx480 is 10% fater than a 5870 so surely a heavily overclocked gtx470 should match a 5870 thats why i think there is something wrong,is the 258.96 the best drivers for the gtx470

I agree, I would have expected a heavily overclocked 470 setup to beat 5870 especially in SLI vs CF

I guess if you are comparing to an overclocked 5870 CF setup also then it will be much closer.

One thing I think is pretty certain though - if you were expecting a boost going from 5870CF to 470SLI then I think you will be disappointed.
 
Just looked into this as i'm running a GTX470 in SLI.

Don't know if this has something to do with it, but if I run Kombustor (furmark) at less than a screen res eg 1280 x 1024, then it only runs off 1 gfx card (gpu 2)

As soon as i go into 1920 x 1080 ( up to 5760 x 1080 as im running 3 monitors) then it uses both gfx cards to 100%

Also fries the top one, but thats another story :p
 
I don't know what you expected you have downgraded your video cards to a slower model and you’re moaning about worse performance. I can see what your saying about overclocking etc and my immediate thoughts were your cards might be throttling back (i.e clocking down) as the heat builds up from the strain of benchmarking. Some of those apps your running are very GPU intensive and the heat the cards generate in those situation don't normally occur in actually games.

Try running the driver versions quoted in the reviews you have seen and see if you can replicate or get new the results quoted in the reviews.
