I don’t know much about hardware so, please, be gentle!
I’m thinking of getting a second GPU to cut (Blender Cycles) rendering times in half. After some research I found out that:
- each GPU renders an assigned tile in Blender (hence the reduced half time)
- the new GPU has to be of the same type (Nvidia, in my case)
- Two GPUs can generate more heat
- ‘I need to check the power’ (not sure what that means)
I own a
‘GA-X99P-SLI LGA2011-3 ATX’ Motherboard, with a
‘Palit Geforce GTX 1070 Super JetStream 8GB GDDR5’ Graphics Card, and a
‘NH-D9DX i4 3U 92mm Intel Xeon’ CPU Cooler
Here are my questions:
A. Should i get the same GTX 1070 or should I go for a faster one (e.g. the 1080?) I was thinking of buying the same GTX 1070.
B. In terms of heat, will the PC be ok or should I do something about it?
C. In terms of power, what should i do?
D. For rendering in Blender, do i have to physically connect the cards via SLI, or they don’t need to be connected?
Many thanks for any comments and help,
