Question CPU/GPU bottle neck?

[Armymen]

Here is my current setup :

Monitor : MSI Optix MAG342CQR (3440x1440)

Computer MSI Meg TI5 11TD220CA (fancy alien looking case)

CPU I7 11700K

32 GB DDR4

NVIDIA GeForce RTX 3070 (8GB)

Power 850W

 

Was planning to upgrade to a GeForce RTX 5070 TI (16 GB) or a 5080 (16 GB) as some of the newer games struggle at 3440x1440.

 

Here is my question.

1- Is my CPU fast enough for that GPU or I would be bottle neck? How can we know what is a bottle neck on a computer without just trying it out????

2- Is 850W enough power or I would need to upgrade for a 1000W (that case need a SFX Power Supply). 

 

Thanks

that depends entirely on the task and cannot be answered without knowing what the task is. anyone who answers it without knowing is making a generalization based on guesswork

At 1440p there shouldn't be much of a bottleneck, more load on the GPU (depends on the game)

I haven't seen PSU requirements yet, not sure if theyve been published

most likely

Are those newer games using/recommend more than 8GB of VRAM?

Brand, model?

How long GPU does that case support?

1- ahh  lol

2- I try the new Indiana Jones games and was struggling to play more then Medium. I think that is due to my resolution and having only 8 GB in the video card.

3- Good question. It is very hard to get to the Power Supply. All I know is this :     850W 80 Plus Gold certified (SFX)

4- Also a great question. I have lots of room as the video card is on the top in it own chamber. So the lengh should not be a problem. That case in a different trim can fit a 3090.

I said that your CPU is fast enough, just not 1000% guaranteed ~ I'm sure new GPU will help run the Indiana Jones or even more demanding without changing anything else

VRAM overflow can really reduce FPS, like drastically regardless if before VRAM overflow you had 200+ FPS

850W gold certif is decent, MSI PSUs are good, so if it's using MSI PSU, it perhaps is fine?

yeah, but cards still have rated mm length, if that chamber is small they'll just use small GPUs to fit it, but small GPUs aren't always cheapest, although usually they are since they're the 2fan versions

there are almost always bottlenecks. for a 11700k expect 20-30% on a 5080 at 1440p,  and if you are hitting the max refresh rate already on ur monitor on the games you are planning to play.

 

the 11700k is slightly slower than a 7700x in gaming

 

 

the 850w psu should be fine, but no guarantees.

Would there be a different cpu compatible with that socket where I would have limited hit?

 

Just try to extend my current computer setup without having to replace everything.

1- Is my CPU fast enough for that GPU or I would be bottle neck?

Yes and No.
This Question can NOT be answered without knowing exactly which Game you mean at which resolution and which graphic Settings.

Also, if you're willing to change Graphic Settings.

And how much fps your Target is.

 

These Questions are seperate for every single Game.

Because it depends entirely on the Game and Graphic settings, where the Bottleneck is.

Example: Do you play at 4k Ultra with 40 fps? No, your CPU won't bottleneck in almost all Games.

You play in 640p Low at 300 fps? Yea, it probably will. But you will have much more fps than in 4k. Bottleneck, but more fps. Why is the Bottleneck bad, if you have more fps?

 

A Bottleneck can't hurt you, and won't hurt your Hardware. Why are the fps less important than not having a bottleneck?

That's the wrong question to ask. You should ask how to get enough fps.

That aside, you're always gonna have a Bottleneck, it's not possible to not have one somewhere.

 

 

A CPU-Bottleneck is always self-made. Take my example above. 300 fps, GPU is bored, but CPU Bottleneck. 300 fps is plenty smooth, isn't it?

You don't want a bored GPU? Give it more to do: Use high/Ultra instead Low. Use your Monitor's native resolution instead 640p.

GPU still bored? Every Graphic Setting on max? Use Mods, use DL-DSR, which will upscale to a higher resolution than your monitors, and afterwards scale down, it will look sharper, and GPU has to do more work.

 

YOU can decide, where the bottleneck is. In Every single Game.

 

 

Here's what you can do right now:

1. chose any Game and start it

2. Reduce Resolution down to the lowst. 720p? 640p? 480p? Whatever the minimum is. Also, Anti Aliasing OFF, DLSS OFF, FG OFF. Keep all other Settings at Ultra or High, or whatever you want them to be.

3. Play the Game, and have MSI Afterburner open to check GPU-Usage. GPU is bored at these Settings? Perfect. This is what you want.

4. Look at the fps. These fps is what your CPU can do. This is your CPU's Maximum fps because this created a CPU-Bottleneck.

5. Are these fps enough for you? Perfect, you don't need to upgrade your CPU. Not enough fps? Then why upgrade your GPU, if your CPU can't even hit what you want? 

 

Up to these fps your CPU can do, that's what you can work with. Up to that maximum, you can work with ANY GPU on the Market. Just increase Graphic Settings to give the GPU more Work to do. Or just enjoy a GPU that's more quiet in this Game.

try it out.

or let others try out who have the same (or almost same) Hardware.

You can't read on Paper what bottlenecks. And stay away from "Bottleneck calculators". They are useless and don't work.

If it's not a cheap noname trash, 850w is PLENTY.
