1080ti Bottleneck?

[Hikio]

I'm planning to buy another Asus GTX 1080ti Strix to my rig, which has a Ryzen 7 1800X. I'm not quite sure though, will my 1800X bottleneck two GTX 1080tis? I don't want to spend another 700$ and experience a bottleneck. I would appreciate if someone with knowledge about this particular topic, tell me if I should or should not buy another graphics card.

Well that totally depends on usage and resolution.

At 1440p and 4k you wont be bottlenecked as much as 1080p, if at all.

 

That also depends on which titles you game at, do you need the upgrade?

I don't think you will be bottleneck if not much. 2 x 1080ti does not equal to 2 x 1080ti performance if you know what I mean. You will only be having like maybe 1.3 x 1080ti or so? So your Ryzen 7 1800X should not be a bottleneck.

Bullshit. In most applications SLI works just fine and gives you about 90% 60% improvement.

With my 4960X @ 4.6Ghz, there are games that will be CPU bottlenecked, not many though. (1440P monitor user btw)

 

Games like GTA5 is held back by my CPU, so I do not get full GPU usage for both cards. It does use 99+% when disabling SLi.

 

Though, anything that is more graphics demanding are not held back by my CPU.

(GTA5 is sort of both but there are more CPU calculations it seems to keep track of many NPCs)

 

So, I don't think 1800X should be holding back 2 x 1080ti apart from low graphics demanding game.

Just accept that you might not get 24/7 144/165 fps, and it won't matter.

Haha. Sure.

That really depends what games by games bias.

One way to test it out is to find out your CPU load vs GPU load. If your CPU is high but your GPU load is low, that's an indication your CPU might be bottlenecking your GPU.

Should be fine

and if it does bottle neck a bit your fps will be that rediculasly high it won't matter 

 

and ou have gpu head room for future games

I don´t think that this is a bottleneck. 1800x is a very good CPU and can keep up with the power of them two ti´s
