[HELP] is it possible/worth for me to add my second 1080 Ti GPU ? (NO SLI)
I create this topic because i have a second unused 1080 Ti GPU and i want to know if it’s possible and worth for me to add it to my system ? (NO SLI, mainly video editing usage)
I apologize for my low english level and thank everyone in advance for your support !
My system at the moment:
Motherboard : MSI Z370 Gaming M5
CPU : Intel i7-8700K
GPU : x1 MSI 1080 Ti Gaming X (connected in my top PCI_E1: PCIe 3.0 x16)
RAM : 2 x 8 Go DDR4 3200MHz CL16 Corsair Vengeance
PowerSupply : 850 Watt Corsair HX850i
Cooling : Corsair H115i
Storage : – SSD Samsung 960 EVO M.2 250Go (connected on my M2_2 slot Pcie )
– HDD 2T0 on SATA
Monitor : 2k 144hz ROG SWIFT PG278Q
If i add my second 1080 Ti on my second PCIe slot, will it be compatible with my system ?
MotherBoard slots : 3 x PCIe 3.0 x16 slots (support x16/x0/x4, x8/x8/x4 modes)
Question 1 : So apparently its ok but i will be in x8/x8 mode, is it better than only one GPU in x16 mode ?
PCIE Lanes :
Question 2 : My CPU as a max of 16 pcie lanes, if i’m in x8/x8, my cpu will be able to use my 2 GPU and my SSD correctly ?
Power supply :
According to Cooler master power supply calculator my 850 watts will be enought for my dual 1080ti (it recommand 700watt)
My usage of computer : I used to have a gaming usage of my PC, but nowadays i mainly use it for Première pro video editing (80%) and sometimes gaming (20%)
I know that without SLI, i wont be able to have better performance in gaming situation, but my goal is to mainly increase my video editing performances.
Question 3 : If we consider my system compatible with this dual GPU setup, will it be worth for me in term of video editing performance ?
Windows & Premiere pro configuration
Question 4 : After connecting my second GPU to my system, what settings on windows and première pro should i do to totally benefit from my dual GPU setup ?
Thanks for all your help and advices !
(Bonus question : if i give you 500$ to upgrade my configuration, what would you change ? :P)
