I have Vray for SketchUp 2014 and getting ready to purchase SketchUp 2015. Will I be able to use my existing Vray license and dongle and just download the new version of Vray, or will I need to purchase the newest version?

Meaning what? My copy is licensed for 10 nodes. What is the change? More nodes, I hope.

Just a suggestion. I purchased 4 Dell R900's on eBay for $150 each. Each unit has 4 Quad core CPU's, so 16 cores each, with 16GB of ram each. That gives me 64 cores for my distributed rendering. These are huge beasts though, at 90lbs a piece, and freight was another $150, so I spent about $750 total to get 64 cores of processing power. So far, fast as hell, even running at 50%.

But I am running Windows 7 Ultimate on each one, giving me access to only two CPU sockets or 8 cores on each machine. I am in the process of installing Ubuntu Linux on each machine, then Virtual Box to run my Win 7. This should "fake out" windows and allow me access to all the cores. Send me an e-mail if you want to know how this all turns out!
