Hi Guys,
 
I currently still have my X58 gaming rig with an Intel i7 920 DO and want to upgrade to an EVGA GTX 1080 Ti FTW3 gpu.    My EVGA Hybrid GTX 970 cannot run my Acer X34 Predator native res of 3440 x 1440 P.  Do you guys think I will run into a cpu bottleneck or will I be fine?
 
Thanks
Jerome

If going for a 4K monitor I would say a 920 would suffice, but 1440p is where you sacrifice the resolution on favour of more frames. The best CPUs today are bottlenecked at 1080p and a first gen core i7 is really going to struggle, even at 1440p.

Actually the resolution can effect a CPU bottleneck. If you run at a lower resolution and lower graphics settings you offload more stress onto the CPU. When you want to test for a CPU bottleneck it is best to set a lower resolution and graphics settings for this reason.

I get that. CPU defines the max fps you will ever get. The GPU running beyond it's means can further limit the max fps. The CPU is always the bottleneck until the GPU is.

But saying a CPU is bottlenecked at 1080p or 1440p makes no sense unless you are bringing a GPU into the equation. It may bottleneck a 1080ti but not a 1070, a 1070 but not a 1060, etc.

The OP wanted to know if a 920 would bottleneck a 1080Ti. The answer is yes.

I agree. My formatting on the post leaves something to be desired, if you look above the quote I did say a bottleneck would be likely. It's just hidden up there!

That wasn't directed at you as much as it was to somethingc00l

I still think it's phrased terribly. "for a 4K monitor I would say a 920 would suffice" ... "a first gen core i7 is really going to struggle, even at 1440p."
 
If it suffices at 4k it will suffice at 1440p, FPS will be the same or higher at 1440p as it is at 4k.

If your FPS is the same at 4K and 1440p then something else is holding you back, like your CPU. If the FPS is the same then explain why it is nigh impossible to find a 4K monitor capable of frequencies greater than 60Hz. Most people even recomemed 1440p over 4K simply because graphics cards cannot render enough frames at those resolutions. Are you also going to claim that 1080p is comparable to 1440p?

• Personal Attacks - Personal attacks often lead to the trading of insults, and can throw the discussion of a legitimate topic off-track.  Personal attacks can be defined as issuing a single or repeated personal attack or attacks aimed at another member, rather than at their opinions or ideas.  Criticizing a member's post is not considered a personal attack, but using terms such as "child," "idiot," "fanboy," for example, or any other derogatory term designed to discredit a member, is not permitted.  Furthermore, comments of a racist or sexist nature, as well as derogatory comments about national origin or sexual orientation, will be dealt with harshly as in a ban from the forums.
• Trolling - Trolling can be defined as when a member posts inflammatory, extraneous, or off-topic messages with the primary intent or consequence of provoking other users into an emotional response or of otherwise disrupting normal on-topic discussion. Trolling can also be accomplished by harassing another member by following them through various threads, creating threads directed at another member or group of members, or intentionally creating the same thread in various forums despite being warned or told to post in the correct forum.  Members who feel they are being "trolled" should contact a moderator immediately, as this is the only effective way to prevent this behavior.

So increasing the resolution does make a difference. We got there eventually.

I'm glad you were finally able to understand why saying it will bottleneck without defining a resolution is a useless statement.

I suggested a resolution to use with a 920, which you then promptly suggested that it doesn't matter. Make your mind up.

I did not say it doesn't matter, I said the CPU doesn't care about resolution. The GPU cares about resolution, the CPU will return the same FPS at any resolution until GPU limit kicks in.
