Toshiba Satellite.
I forget the screen size - I think it's a 15" screen.
12GBs of RAM, i7 Intel
Windows 8.1; 64-bit
It will NOT do Iray very well, it's on-board video, on-board sound, and the video is NOT Nvidia... so if you want to use Iray, I would NOT recommend it. A simple portrait (bald male, one shirt, NO background) takes this machine about twelve HOURS to do. And yes, I fiddled with the settings and materials and all of that, to avoid the usual pitfalls that increase render time.
If you're going to use 3Delight, then this machine does a great job... but I would not recommend it for Iray. I don't know how it would perform in Octane, as I don't own that, and I have not yet tested it on Reality, so can't say about that, either. But for Iray it has to do everything CPU-only and that dramatically increases render times (and is why I am still a 3Delight artist).
Other than the no-Iray thing, though, she's a very sweet little laptop and she's a beast for memory management and large scenes...
