Thea Render at BaseCamp 2012
-
Nice! I believe iRay is the only GPU raytracer to require workstation-type GPUs. The rest work best with gaming-type ones.

Thanks for the clarification Notareal!
-
Excuse my ignorance, but I couldn't really find any info on this:
Is this the new version of the Thea SketchUp plugin? Or is it a new independent product, which will be charged for? IOW, if I buy Thea + SU plugin now, will I have to pay again to get this new tool?
BTW, a pity that there is no Thea for LightWave.. -
It's a new version of the current plugin and (AFAIK but there is notareal to correct me) these features above (both plugin and GPU rendering) will bee included in a free upgrade for existing license holders.

In certain GPGPU operations 680 is indeed "crippled" and inferior to 580, but fortunately this has no affect on Thea GPU engine.
Could you elaborate on that?
I just bought a 3gb GTX580 for its "said" greater GPGPU performance.
Was that a bad move...?

Thanks Csaba
Guess it's time to delve into the mysterious realm of graphics cards again, to pick the right one
Is this site http://www.videocardbenchmark.net/high_end_gpus.html worth looking at?
Looks like GTX670 would be a good choice? -
how can i check if my motherboard would support one of these high end GTX cards??? You see.. i am noob.

GTX580 is not a bad at all. But as used architecture between kepler and fermi is rather different, cuda core to core comparison is difficult. There been talk that GTX6xxx series is inferior to GTX5xxx series, but this seems to be true only in some spesific instruction that Thea does not use. When some new CUDA features are used, GTX6xxx has some benefits. Still Thea tries to be usable for rather wide varity of CUDA cards, so some of these features might not be used at the moment.
As card vs card comparisons are hard to made in this developement phase (propably missing some optimizations and so), I'd rather not say if there any meaningfull difference between xtg580 and xtg680 - as xtg580 works fine with Thea.
Anyhow this does just proof that GPGPUs are so fast developing area that software developement has some challenges and hardware spects do change so fast. I believe this was the reason for originally planned Thea OpenCL renderer to CUDA render move. Naturally OpenCL is not in my undertanding excluded from future use, but it just, unfortunatelly, looks not that mature to be used at the moment. -

Any modern motherboard core 2, i5, i7 should be fine or att least there should be a PCI Express bus (v.2.0). Proper PSU is more important, often computers do come with rather low end power suply.
Usually these high end GPU cards do require around 550W and greater PSU... it's best to look on rated specifications at http://www.geforce.com/hardware/desktop-gpus -

It would be very interesting to see a speed comparison between a 580 and a 680...
