How to work with a gtx 560 ti 2GB and a 580 3GB?
on Jun 23, 2012 at 7:39:05 pm

I recently build a new workstation with an Asus p9x79 deluxe motherboard. I have already a gtx 560 ti 2GB installed, but I have just bought a GTX 580 3 GB to join him.

Question: Which one should be the GUI and which one the GPU? What is the best idea?

Might be good to know that I'm running a hackintosh/win 64 configuration, so it's a dual boot machine. I'm also using FCP Studio and CS6.

My first idea was to build a dedicated WIN 7 machine, but I found out that, after doing the hackintosh, Resolve was working even better in OSX than in WIN 7. Anybody had this experience as well?

Thanks!

If you can get it to work, I'd say 560 for GUI and 580 for gpu.

But I don't bother with hackintosh. IMO either run a well configured windows sys or a well configured Mac, but trying to Frankenstein it will only lead to frustration.

In my experience with config guide speced win7 systems, they perform as well if not better than Mac. Key is having a proper config, there are lots of factors including a need for a quadro for GUI and a good ram/bus & pci optimization.

Good luck though, and let us know how it goes.

So do you think a quadro 600 will perform better than a gtx 560 ti 2 GB as a gui card?

I think the windows config guide makes it very clear they expect a quadro 600 or 4000 for the GUI.

I have two Windows systems with GTX 285 (GUI) & GTX 580, and they rock. GTX 285 is not officially supported, but it works nicely. I tried also GTX 560 ti for GUI, and frame rates went down, especially when using internal scopes. So went back to 285..

Thanks Timo! Thats very usefull info.

Did the performance drop dramatically? Or a little?

I also have avid installed, any experience with that regarding the gui cards?

Thanks

Hi,
With GTX 560 ti as a GUI card and 580 as a processing card, and with the internal scopes on, I remember that frame rates dropped a little from real-time playback, 21-23 fps, whereas with the GTX 285 as GUI card it was real-time playback with up to 14-15 nodes, after that frame rates drop a little bit. The material I used was 1080p prores.

I found that GTX 560 ti was actually quite okay when used as a processing card, not GUI. Not as many real-time nodes as with 580, maybe 10 or so.. And also I had the 1 GB version, not 2GB.

Thanks again!

There's one thing I don't fully understand. You say that with the 560 as GUI amd the 580 as GPU, you couldn't get real time playback? The thing I don't get is that right now I have only the 560 Ti installed and I can play up 7 nodes with a 100% blur in realtime. Adding nodes after that my fps starts dropping.

I think I will simply test both configurations in WIN 7 and see the results (and post them here).

[Pepijn Klijs] "You say that with the 560 as GUI amd the 580 as GPU, you couldn't get real time playback? The thing I don't get is that right now I have only the 560 Ti installed and I can play up 7 nodes with a 100% blur in realtime. Adding nodes after that my fps starts dropping."

Is that with the internal scopes on or off? With the scopes off, it's much easier to get real time playback even with one GPU. It's also a bit strange when trying different GPU combinations, sometimes they just don't work together as you would expect. The performance also seems to depend on the specific motherboard and other components. And I've found that it's good to stay with the recommended drivers.

It's with the scopes on.

And I remember that I tried the 'old' drivers that Resolve recommended, but I think I lost my dual screen ability after installing them, so I installed some more recent ones. Sorry for being so unclear, but I've been trying a lot of stuff...
