Two graphics cards, one problem

So after impressing my office with Lumion my boss has decided to purchase a better [suited] graphics card for my computer.  I'm currently running a Quadro 4000 on my computer and it's been, to say the least, abysmal.  I work in Build Mode at 1-3 FPS, and I typically render a scene at around 40-50 seconds/frame.  I used my Radeon HD 5770 at home to get slightly better render times, but it still took around 40 seconds to render one frame.  For a three minute video that meant I needed about 60 hours available to render.  Complicating things, considering I'm still learning the software, any mistakes resulted in often 7-8 hours of lost time re-rendering.

I'm considering buying the GTX 670 after careful consideration.  The 690 is out of my price range ($300-$400), and the 680 is slightly out of that range as well.  So here are my questions:

1. Is the GTX 670 a good card suited for Lumion?  Is the 680 a significantly better card than the 670 and worth the extra money?  Like I said, I'd like to stay below $400.

2. How much improvement over my Quadro 4000 should I expect?  I'd like to see render times significantly shrink as well as improved Build Mode performance.  If I'm only getting marginal improvements I don't think it's worth the investment.

3. Can I keep my Quadro 4000 in my computer with the new card?  The Quadro still performs great, especially with Revit and 3D Studio Max.  Unless the GTX card is equal in performance with those applications I'd hate to just improve performance with one software and sacrifice in another.

Hi amartindill, here are some benchmark results for the 2 cards:
http://www.videocardbenchmark.net/gpu.php?gpu=Radeon+HD+5770&id=6
http://www.videocardbenchmark.net/gpu.php?gpu=Quadro+4000&id=1549

Maybe you could upload the scene that takes 50 secs/frame and ask somebody with a GTX 670/680 to render a few frames for you?

3. Can I keep my Quadro 4000 in my computer with the new card?
Generally speaking, Lumion does not work well with multiple graphics, so to err on the side of caution, I would not recommend this setup.

i have a gtx580 3gb and after i got my computer ventilated properly, im getting 9 frames per second render time.

Using an EVGA GTX 670 4GB here. It works perfectly fine using all-star build mode, full res at 2560x1600, typically at no less than 30 frames/second. Render times depend on plenty things. I am getting between 1.5 and about 15 seconds / frame at HD res. video rendering. Stills at print resolution take about 3 to 20 seconds. The latter if I use all alvailable reflection planes. The card works fine in Revit and Max as well. Just wishing Lumion would offer SLI-compatibility one day. That would be the day I am buying another such card.

Thanks for your real-world feedback, guys - I'm sure this will help amartindill make an informed decision.

We ended up purchasing the 2GB GTX 670.  I would have liked the 4GB version but budgetary reasons prevented that.  As long as I'm not getting 50 seconds/frame render times I'll be happy.

First test, same scene.  Quadro 4000 took 50 seconds/frame, GTX 670 (2GB) took 6.8 seconds/frame.

A scene that originally took 4 hours to complete now takes 45 minutes.  Vast improvement.

Hi All,

I am beginning to wonder whether there is actually threshold to the render speeds achieved with these graphic cards in lumion. A law of diminishing returns seems to apply here. I use nividia 465GTX with 1GB. The render speed I get is  between 6.8 seconds to 15 seconds per frame in 3 star mode HD depending on the complexity of the scene. I get between 0.28 seconds to 3seconds per frame in 1star HD.

I expect you guys to get much faster speeds with 570GTX with 2GB or 680GTX with2GB.

Regards,

Alickn.

I have seen some very interesting differences in identical cards...there are so many other variables.

I live in ontario...my computer sits right next to a sliding window....when the fans start to whine up to speed and stick there I just slide the window open a crack to let the cold air pour in......Witnesses always chuckel when they hear the fan immediatly start to unwind.

It would be an interesting study.  It would be nice to get a standard scene that would somewhat stress even the toughest cards and see the results.

Quadro cards became even worse with Lumion 3. I have a very powerful computer with a Quadro 4000, but its performance with Lumion 3 is awful. It wasn't that bad with version 2.0 and 2.5. Last week i decided to buy a GTX 670 card for another computer, and i see that it's at least twice the Quadro 4000 in terms of Lumion efficiency.
Bottom line, if you have a Quadro card which works okay with a prior version of Lumion, and you consider to upgrade Lumion, then you should also seriously consider to buy a high end gaming card.

It's a night and day difference.  Render times don't tell the whole story.  I was lucky to get 1 FPS while working in 3.0 with the Quadro 4000.  It was unbearable in complex scenes.  At it's worst it made it hard to tell if I had the lighting correct.  The GTX gets me, on the same scene, 8 FPS.  So much easier to navigate.

We run a 580 which is hot and power hungry and a 670 which is cooler and faster.
I think of the latest Nvidia 670 is the best price performance from the current range.
