I´m building a new computer to render with Octane+C4D and compose the output in AE, with heavy emphasis in gpu power for Octane.
What do you think overall? your opinions are more than welcome.
Beside the 4 GTX 980 TI I have an extra SSD m2 for the AE cache and 128 GB ram. Will Octane benefit at all from an extra SSD for cache? And from the 128 GB Ram??

Do you think cooling can be an issue with the current setup?
Thanks a lot in advance!
