1070s now seems to give a good value if You do not need more than 8GB of vram & focus more on speed.
if amount of vram is important & You plan to have a need for more than 8GB then look at 1080Ti with 11GB.
last but not least think about upgradeability & portability of Your box. For instance if You plan to expand sometimes it's worth to invest into more powerful cards that would allow You to keep them & add more rather than replacing existing
Another thing, if You have to move Your box, again think about less but powerful cards to save some space & minimize dimensions of Your machine. Also, what is Your upgrade cycle? if You plan to use Your computer for three years, getting higher end cards might be wise idea.
it's hard to recommend without knowing what You're up to, but overall try to look at reference/founders 1070s or 1080tis.
let us know if You would still have some questions.
Hi!
Thank you very much glimpse for your reply! I think I will use the computer about 4 or 5 years (I'm not used to PCs, but I hope it will work for a long time). For me the amount of vram is quite important because sometimes I work in projects with a big amount of polygons...
Regarding of the amount of GB and CUDA cores, I have a big question about how the GPU render works:
I understant that when you render with Octane, all the graphic card works like one? So with x4 1070 I will have 32 GB vram, isn't it? and 1920x4 CUDA cores? So technically (and cheaper) is it better to have 4 1070?
Thanks!
