Yeah, I thought so. Most of us who are enthusiasts probably do not have the power you guys possess (or the desire to plop down $500+ on a video card when you're only a hobbyist).
That being said, you can't argue with the investment or the results.
I actually could afford a $200 - $250 card, I'm just cheap. LOL!
and it dose not log the amount of convergence.

There's another group that would think nothing of shelling out that much for a video card...gamers.

And there's also the odd handful of us with more money than time or sense (or is that a handful of us odd types?) who wouldn't object to upgrading the video. Actually, I'm holding off, pending the DAZ offering Spooky mentioned in one of these Iray threads - and there's always the chance I'd be able to pay for such a card with store credit that resulted from a discounted gift card . . .

Agreed. I just need to replace the display card now (still counting days, lol), for many OpenGL related reasons. The render card will wait.

Those GT 730 cards are actually kinda cheap on Amazon.com. Anyone do a benchmark with those or can point me to one?

There are some OpenGL benchmarks around with the 1GB and 2GB cards, I was not able to find any on the 4GB card.

I use Asus STRIX for a reason... 0dB.
http://www.asus.com/ca-en/Graphics_Cards/STRIXGTX970DC2OC4GD5/
Basically, if I'm running simple software like audio production or a video game like Crysis 3, I'll never hear it. When I render and burn 350 Watts in my PC, I can barely hear them as the fans kick in (and not at a high speed or anything) to keep the temperatures below 70. At full speed, the fans on the STRIX are very loud, but they will also cool the GPU to 40C while rendering at full tilt.
My biggest concern is keeping CPU fan noise down. I hear those when I'm doing a lot on my PC. Mastering your CPU Overclocking/Fan Control software will go a long ways. I'm an Asus man, so AI Suite 3, and GPU Tweak. My PC is overclocked to 5Ghz, and I leave the fans on Turbo (can be loud if the CPU loading is heavy).
By the way... under clocking an expensive PC will also get you a lot of quiet.
I have a friend who keeps his PC in the basement, and just runs enough cables down to it to use it.

MSI GeForce GT 730 2GB DDR3 [N730K-2GD3/OC]
(Yeah, that's the active cooled GT 730 with 128 bit Memory Interface which only has 96 CUDA-Cores).
Already has been replaced by a
Gainward GeForce GT 730 2048MB SilentFX [426018336-3224]
(passive cooled, 64 bit Memory Interface, 384 CUDA-Cores)
once my favourite salesman has been aware of his mistake [I told him :-)].
The stats are for the MSI GeForce GT 730, I'll retry the render with the Gainward GeForce GT 730 SilentFX once I find the time.
A first test with the "Material Ball" scene resulted in that the Gainward is around 25% faster:
Total Rendering Time: 59 minutes 14.19 seconds
Unfortunately the render was completed by reaching the maximum number of samples at between 85.0 and 90.0% convergence.
I added it for comparision. Seems pretty close to the final.
From another test render I got that it might be enough to let it render up to a Rendering Converged Ratio of 88.0 % instead of 95.0 %. I guess it depends on the scenery and lighting used. There aren't any noticeable differences, but the 88% one took only nearly half the time to completion. ("13 minutes 56.57 seconds" instead "23 minutes 56.85 seconds").

Sorry, not Spooky; it was DAZ_Jon here
Ok. Same machine, "new" card. I'd been borrowing my 980 out of the gaming machine while I looked around, and I finally bought another card to replace it. Honestly, I was pretty close to getting a Titan X, but there was some shred of sanity left in me, it seems, and I held off. Decided to go powerful, but lower priced, with an eye towards nVidia's next gen card in 2016. I was just about to pull the trigger on a 970 (hoping it's 3.5 + .5 memory wouldn't bite me), when I noticed a refurbished 780 with 6GiB of Ram. As far as I can tell, only EVGA made one of those and there wasn't a lot of them. At around $100 more than a 970, I went ahead and grabbed it :)
Here's the benchies:

Please, can anybody help me? I've installed D|S 4.8 and tried to render something via NVIDEA IRay. Simple scene took about 2 hours of rendering. In log file it says that I'm using only CPU.

Please help :(
Two hours is not an unusual time for a regular scene at 1000x1300 or larger on a quad core CPU. Turning on OptiX acceleration in your advanced render settings can help a bit.
It says your graphics card only has 1.9 gb VRAM, so there aren't many renders it will be able to handle without running out of memory and switching over to the CPU (possibly none). Since that's a laptop GPU, though, and it's saying "there is no GPU available to the Iray renderer," it's possible it's also a driver problem. Some people have had to use different Nvidia drivers in order to get Iray to use a GPU on a laptop (I don't know what version or where to get them, you'd have to google it).

Thank you so much! GeForce 840M was unchecked xD
*Dies*
...Or it could just be that.
Due to testing, by default, any Video card with less than 4GB of RAM is unchecked.
That is not saying you can not get use out of it, provided you are careful, but that with 2GB there are more likely to be driver conflicts which cause crashes, if anything else is also using the video card. (This is especially true on the Mac which forces an automatic reboot on the driver crash.)
Found the time to let it render the scene. So here are the benchmarks for the GeForce GT 730.
GPU only, since my slow Athlon creates a hefty bottleneck trying to help out rendering. Which doesn't help much at all. :-)
For my renders I set the "Instancing Optimization" to Speed and using the "Optix Prime Acceleration" for it's the fastest setup.

CUDA device 0 (GeForce GT 730): 6328 iterations, 50.641s init, 2484.912s render

IMO the GT 730 is okay for rendering simple sceneries at a reasonable amount of time, but not much more.
In my area the next best choice would be a GTX 760 (4GB GDDR5, 1152 CUDA Cores) at around 220 €.
(Less expensive cards lack either the amount of preferable 4GB RAM and/or amount of Processor Cores.)
But I guess than you could even go for a GTX 960 "Phantom" or "Jetstream" (4GB GDDR5, 1024 CUDA Cores) for around 240 €.
There are some OpenGL benchmarks around with the 1GB and 2GB cards, I was not able to find any on the 4GB card.

So, I did some posting. Zarcondeegrissom, I bought a GT 740 Super Clocked video card from Amazon and got it yesterday. When I did this test originally using my GT430 card with 2GB of DDR3 RAM, it took over 2 hours. Was thinking it was the card after reading thru these posts. Installed the new card and it still took over 2 hours, plus I got the NVIDIA OpenGL Error 3 message.
Before going into panic mode, I decided to stop some processes and kill my screen saver. Let the render run over night.
Here are my results. Don't laugh at my rig...lol.
Computer: Dell XPS 410
OS: Windows 7 Ultimate
RAM: 8GB
Processor: Core 2 Quad Q6600 2.40 GHZ
Video Card: NVIDIA Geforce GT 740 SC (super clocked)
CPU (3 threads): 1011 iterations
CUDA device 0 (Geforec GT 740): 3989 iterations
OptiX Prime Acceleration enabled
Render time (including spheres 8 and 9) : 35 minutes, 4.9 seconds
Definitely an improvement. Now I'm thinking the GT430 would've come in at an hour. I have an i5 that I use for my renderfarm. Since it supports two video cards, thinking about switching the two and using both the GT430 and GT740 side by side with CPU.
Here is some data from my PC with an outdated GPU. Kept it from my previous PC.
Win 7 64bit
i5-3570K @4.1GHz
GTX560 Ti 1GB OCed
16GB DDR3 1600 MHz RAM
Complete Scene to 90%
GPU only - 13min 40sec
CPU & GPU - 11min 55sec
CPU only - 41 min
Monitor connected to internal GPU.
From what I have seen here, the results are not consistent with other posts. My GPU seems to be a lot faster than it should.
And my CPU is too slow. Very strange.
The 500 series are not bad cards, they just don't have enough Ram for most scenes, especially if they are also running monitors.
Thought I''d try this while setting up the new/replacement laptop. I'm quite satisfied with the performance so far, especially for a laptop. Wish I could have gotten the GTX 980M, but it would have been $300 more :bug:
Specs:
Model: ProStar 177SM-A

CPU = 33 min 55 seconds (only went to 90% with this one)
CPU + GPU = 6 min 43 seconds
Someone was curious how a 970 compared to a 980, and as I was curious myself, I thought I'd run some benchmarks. Cost wise, it seems the 970 offers the best value; curious on the 960 with 4GB though, and I was initially going for that but considered the extra CUDA cores worth the extra £70. The full 4GB of memory is available on the card, I'm curious though how the issues that NVidia reported affect performance on the 970 and 960.
The scene was allowed to complete in all instances. What is amazing, is how quickly all get to about 75 percent.
Strix 970 - I like quiet.
GT 640 2GB GDDR 3 - passively cooled
CPU I7 4770k (3.9MHz) - water cooled (I don't run it over-clocked as the increase in performance isn't worth the reduced life for me. I do really, really like quiet. :D )
16GB memory
A Titan X or 980Ti is beginning to look tempting though.

I watched SickleYield's video and she reported some say there is a speed up and others report a slow down when using CPU; that may relate to the number of threads the CPU has available; note mine uses 6 when working with both GPUs and all 8 when rendering CPU only. A CPU with fewer threads will switch processes more and the overheads from that may be what outweigh any gains?
I was further curious when testing the difference between both cards and CPU and just the 970 and CPU; so much so that I reran the tests after I obtained the first results.
Thanks for the test dsexton72. I have had this new card in the computer for about a week, and am dreading pushing it. First off tho.
My GT730 issue, It's making disturbing sounds. Whenever I do something in the view-field, the workload of the GPU goes up, and sounds come out of my speakers (clicks, buzzes, etc). I once again, threw an oscilloscope into the computer to watch the power, and it looks good where I can get the probes. So I can only guess I got a bad card, or it pulls WAY MORE then 23 watts when under load. So I can only guess that when the card is stressed with OpenGL work, it is causing realy nasty power fluctuations on the rail the sound-card also happens to be on.
Oddly, this only happens in Studio in the view-field. It dose not happen with web pages, file-manager, etc. :coolhmm:
Zarcon, have you got a CineBench OpenGL score on that card?
23Watts! I'm pushing 120W under load on an old 550Ti :-)

The 23 W may be correct at idle but certainly not under load. The GT 730 is a slight evolution of the GT 630 with better TDP and updated software support. But under load you should at least go over 70W
Sounds more like RF type interference than power problems, to me.
It's an OpenGL sound effect, that the old card's OpenGL didn't support.
Make it STOP, Make it STOP, Make it STOP... :lol:
