Multiple GPU Question
I am currently running my Resolve system with a GTX285 for the GPU. I would like to increase the power of my system. I have a Quadro 4800 in another system of mine that I could easily pull. I was thinking of purchasing a Cubix expanded and putting the GTX285 and Quadro 4800 in it. Is it a problem putting 2 different approved cards? This is an interim setup till I can afford to purchase 2 Quadro 4000’s.

I’d buy one gtx470 from ebay instead. The same result.

The FX4800 is slower than the GTX285 so both will run at the same FX4800 speed.
You should consider getting another GTX285 as two of them will give you alot of performance. You can still get them at eBay apparently.

If you have a Cubix expander and have at least one 8 pin PCIE power plug, you should go for a GTX480 instead of 470.
There have been tests done by a known independent 3rd party with 7.1.2 that showed the GTX480 to be embarrassingly faster than a Q4000. These results were shared with some people at BMD but will likely never see the light of day beyond there. The realities of sustainable product support and advertising dollar flow will see to it. Just how it is.
If there is someone in Hollywood who would like to set up the tests that Sascha Haber posted I will be happy to loan out a GTX285, GTX470, and GTX480 for comparison. (I recently sold my Q4000, but we will need to include it…best if whoever does testing already has one) Same machine, same files, same tests, same GT120 for GUI. Only the GPU will change. This would need to be a Mac Pro, preferably with a Cubix expander but if not I can bring a PSU for the GTX480.
I think this is the only way to get REAL numbers out there that have not been influenced by advertising revenue and “give us a good review or no more test units” type threats. This will need to be a person or persons with some technical skills. I would like to just loan out the cards and perhaps some AGPM kexts but have no other input.

It needs too much power, extra power modification will take place. Do not worth it if put inside mac pro.
Inside CUBIX – yes. -
By the way, did anybody mention, that resolve do not complain anymore about unsupported GPU when started with GTX 480? )))
-
actually the 470 , give me “only” 2 nodes more (all node with blur blur) than the 285… so i guess that 2×285 is faster than one 470 …

Is there a good working combo?
Say I have access to a Quadro 4800 and Quadro 4000.
Then add a AMD 5870 and 5770.
Is there a magic set-up without having to go to a Cubix?
I also have the future option of two Quadro 4000 in the same 12core. -
Two Quadro 4000 AND the GT120 would make an awesome in-the-box setup.
Without letting you use an external Raid of course.Tomorrow I will get my 470, and when the test turns out as expected, that saved me the cost of two quadros and the cubix.

Please let us know the details with the 470 when you get it-

The Q4000 has a lot more GPU RAM. The extra RAM comes in handy when using lots of mattes, parallel mixers, or high resolution images (4K/5K).
On the other hand if GPU RAM is not an issue for you, you can consider putting in two of the 470s in the Cubix (officially unsupported BTW), and you should get a pretty fast system!
