To your knowledge, would my Thermaltake toughpower XT 875 watts be strong enough to magage the new GTX 690, i have an I7 3.4ghz, 16 gigs RAM.

Just to be sure before i put myself on a waiting list to get it.

Hi Sacha, applications that do support 2 GPU cores (such as the 2 x 680 GPUs in the GTX 690) basically use 1 GPU core + 50% of the onboard ram for rendering frame 1 and the 2nd GPU core + the next 50% ram for rendering frame 2, and so on and so forth.

Unfortunately, you will not see any significant performance gain with a GTX 690 (compared to a GTX 680), since Lumion doesn't perform any better with 2 GPU cores. And due to the ram mirroring, you will only benefit from 4GB of the 8GB ram.

Anyway, I just wanted to make sure you were aware of this before purchasing a new card - some of the other 3D applications that you use on a daily basis may be better equipped for taking advantage of the 2 GPUs on the GTX 690 :)

If i read you right Morten, there won't be any difference between the 680 and the 690 for Lumion, but might be usefull for running AutoCAD... will there be a really big difference between my quadro 4000 and the 680 (690)

Applications basically have to be customized for multiple GPUs, otherwise there won't be a performance gain, but I can't find any recent information that confirms whether AutoCAD, Revit etc gain a performance boost from that.

It might actually turn out that the GTX690 will perform slightly worse in Lumion since
its settings are a bit lower as the GTX680 Iirc.
Yes, the GTX680 will be significantly faster for Lumion as your quadro4000.
