Question 7700x with 4090 triple monitor performance?

[DAG93]

Hey everyone, trying to figure out a hypothetical here before helping my friend commit to a new GPU. He just upgraded from a 17 3700k to a 7700x. He was forced into getting a new GPU about 4 years ago when his last one died and currently has a 2080 paired with the new 7700x. He wants to go ahead and get everything current with a new GPU. He has been playing most games at standard 1920x1080 but he has triple monitors that he is getting less and less use out of due to the age of his hardware and games getting harder to run. At standard 1920x1080 his cpu will become quite the bottle neck. My question is will the cpu load shift more to the 4090 in a triple monitor set up like it does on higher resolutions like 4K? Logically I would think yes but I wanted to provide him with the right answers so I can here. Triple monitors would be 5760 x 1080. Thanks for any help!

I guess I am not understanding the bottleneck concept here.

Your friend already has a 7700X, which is pretty much second only to a handful of CPUs. And he wants more GPU performance. Whatever he can afford is his limit, bottlenecks of the nature you are talking about are basically not a thing.

If you want less of a GPU bottleneck, get new higher resolution monitors, or a 21:9 1440p display or something.

Sorry if I wasn’t clear. From what I have seen benchmark wise is the 4090 will bottleneck pretty much ever cpu at 1080p. Also from what I have seen usage shifts more towards the GPU at higher resolutions thus the cpu becomes less of a bottle neck right? My question is will that principle effectively work the same on the triple 1080p monitor since the total resolution is 5760 x 1080.

Even if the total digital resolution is 5760 x 1080, if your buddy just plays on one of the three screens, it's still 1920 x 1080.

You are looking at this from the wrong perspective. You want to avoid bottlenecks, okay. Right now the bottleneck is the GPU, according to your friend. Getting a faster GPU is the only real solution there. There is practically no CPU improvement to be had until the 7700X3D releases.

Doesn't matter if the CPU becomes the bottleneck, your overall performance goes up. No other thing to consider.

If you are asking if he HAS to upgrade his monitors to avoid a bottleneck, the answer is a possible yes. No reason for a 4090 at 1080p. Triple screen is 3/4 of 4K, which is alright, but anytime he is running a single screen, he should look to a higher resolution. Or he can simply run with EVERYTHING turned on, including ray-tracing and still get a respectable FPS.

Consider a 4080 and a 1440p 240hz display or something. Or a 5120x1440 ultrawide to replace the three screens. You can always have the other screens on there for non-gaming purposes.

I know people say the workload ‘shifts’/‘moves’ to the gpu when going to a higher resolution but I feel that term is misleading. All that happens at a higher resolution is the gpu becomes maxed out at a lower fps meaning the cpu runs at a lower usage because the fps are lower not because the resolution is higher. Going from 1080p 60fps to 4K 60fps isn’t going to reduce the cpu workload, at best it will stay the same but it may even go up in some games. It will use significantly more gpu resources.

You want a 4090 for one single 1080P display? I'm lost on why you would do this. (is he a pro gamer who makes money???)

It 3 monitors but yeah they are 1080p. I suppose the extra pixels he has to push horizontally doesn’t matter even tho it’s more then 4k. He bought it away he is going to get a tv for more casual gaming as well. Thanks for everyone’s input

gotcha must be racing sims or something most games don't support the game on 3 monitors

4K is literally 4 1080p displays.

3820x2160 ~= 8.2 million pixels
5760x1080 ~= 6.2 million pixels
5120x1440 ~=7.4 million pixels

Single ultrawide gets you there for the most part, no bezels, and won't have much a performance impact. Just the cost. But you are talking 4090 money.
