Question Is this a GPU issue with 11 displays?

[FrequentFlyer]

Hello,

I have a setup that includes 11 overall displays, all are 1920 * 1080 besides a couple that are 1920*1200 and one 4k tv. These displays are connected to four GTX 1080 cards and the CPU is an Intel Core i7-7700 both of which I believe are slightly overclocked. The issue is that we are running into major framerate issues when we use all of the screens (flight simulation). Someone told me a while back that it might be a GPU issue but I have a hard time believing that and would rather think that the CPU is the issue but I am no expert on this. Additionally, maybe I have some power supply limitations for my 1000W given that I have 4 1080s?

Any help is appreciated!

You might need more power. I would suggest you put your PC build specs into https://pcpartpicker.com/ and it will tell you your expected power requirements - as a place to start. See also: https://pc-builds.com/calculator/Core_i7-7700/GeForce_GTX_1080/0KR0Uulx/8/ - the result is "your CPU is too weak for this setup"! You should upgrade the CPU!

It wouldn't let me put in four graphics cards to the site you said. However, using https://outervision.com/power-supply-calculator , it said the recommended PSU Wattage is 999 Watts so, that doesn't seem to good and maybe should look for a little more.

Unfortunately, your link wouldn't open up on any browser on my computer however, I have been told in the CPU thread that my GPU was the issue...... I posted here because I was hoping to address both audiences.

Hopefully a new PSU (1200W or more) solves your issues
