Tech Question re: Dual GPUs

[bauwce]

Hello there, I am new to the forums but came seeking help. I recently went to a vray seminar and learned that through vray you can redirect to your gpu for rendering. I am actually ordering a computer tomorrow and wanted to know if I reroute to gpu for rendering and I have two will it use both to render. I am debating between an nVidia 980m or an nVidia 970m (sli) aka two 970m gpus. I hope someone can help and thanks in advance.

No problem, V-Ray can use as much GPUs as there are in your system (it will render better with SLI off).
Please note that the memory doesn't stack - two GPUs, four gigs of mem each result in 4 gigs of usable memory for rendering, not 8
