Such cheep cards are a complete waste of money, imo, because the render speed will be very slow even for simple scenes. Start looking at $250 and up.

Then i get something like GTX 560 2GB DDR5, 256 bit, engine clock 820 MHz, memory clock 4008 MHz
~ 215$

hi abreukers!

thank you for teh fast answer. it means, that i must wait a bit.. you mentioned there is a version for kepler too, it is downloadable as demo maybe?

thanks,
Rafael

Kepler cards are out for some time now. A demo version would be kinda cool by now?

How is the current state in regards to performance on Kepler cards?

Hi Heretic,

At the moment a 680 will only perform about 60-70% as well as a 580.

Cheers
Chris.

Next week I'll buy a new computer. I would like to ask whether it makes sense to invest money in the old 5th series. Is the aid of graphics cards of 6 certain series? It's only a matter of time, or just experimenting?

I do not want to give too powerful PC graphics cards in 3 SLI involvement of 5 series. If the transition system, rendering only a matter of time, buy a video card instead of 6 series and wait for the new version OctaneRender.

Or I'm wrong? I can still decide ....

PS: Sorry for English. It is the result of Czech + google translator

Thank you for your answers

Cheers and thank you a lot. I read that part abotu performance, yet the first mention was from like May this year.

Actually then am unsure on Octane and how to proceed...

1. Does the kepler version run nonetheless?
2. I need to buy to test? No other way?
3. Any eta on a stable efficient build for kepler cards?

Basically am curious in trying Octane for a while, but lacked the system. Now with a GTX680 with 4GB RAM I was sure/hoped to have a suitable plattform

Any cool suggestions to help me in my misery?

Heretic,

1. Yes, the kepler version runs fine. At this stage it is looking stable.
2. Yes, as abreukers said - at the moment the demo does not support kepler so unless you can get your hands on a fermi card there is no way to try octane before purchasing a beta license.
3. The build is seeming stable (not many reported problems), it is just not an official beta release.

Although the performance for kepler is not as good as fermi at the moment, a 680 will still do ok and will be very workable for realtime scene manipulation.
Personally i own a 670 for my home PC - but my decision there was more for the gaming performance. It works with the kepler test build no problem, it's no 4 x 590GTX setup but it gets the job done.
The suitability of the 680 is dependent on what your needs are. For large scale commercial projects where render time turnover is important the 6xx series are perhaps not the way to go.

Cheers
Chris.

But what about future development for the gtx6xx?
Is it only a matter of octane development-time till these cards perform better than the gtx5xx?

Second question would be when do you expect the next performance boost with future grahics cards?

Hi Rob,

Sorry, I don't have any concrete answers for you here. The problem is that this kind of optimization work is not 100% predictable.
We are hopeful about increasing performance for kepler but cannot make any guarantees.
I am hesitant to talk about any time frames because i do not want to start making suggestions to the community that may fall short.
I hope you understand.

Cheers
Chris.
