currently only tesla cards with 4GB and i'd wait a bit until fermi based cards are available with more than 4GB ram.
We also need to make some modifications to octane in order to render larger than 4096x4096

Radiance

Tesla cards and supercomputers have up to 24 GB

Another question about ...

Florinmocanu wrote:a GTX 465 has around 60-65% from the performance of a GTX 480. But, it comes with just 1 GB of ram, the extra 512 MB of the 480 will really help in larger projects.

What do you think, what amount of ram on card will be enough for IMAX resolution (10,000×7000) projects? 2? 4? 6? 24GB?

Hi

What is the most important for GPU rendering performance?
CUDA cores? memory amount? core clock? amount of RAM in host?
