From what i know so far in gaming world , the 2 gpu is the most optimal setup (a lot of game even doesn’t works well with multi gpu). How about for 3d app (blender and other 3d) ? is the same rule applied ? Maybe the more gpu added will increase the render speed , but the enhancement graphic is not linear , but the price is always linear. So how effiecient it is to have more than 2 GPU ? Any has experience with 3 or 4 gpu , how many percentage the enhancement from 2gpu to 3gpu ?
I plan to use 3 x 1080 ti but may cut to 2x if it’s not good option, any advices will be great. Thanks a lot.
