No bottleneck.

A 4K monitor with Gsync would be a better upgrade. 4K because these 30 series cards leave performance on the table at 1440P and especially 1080P. And Gsync because it's the best thing to happen to gaming since SSDs.
 
This is coming from someone who upgraded from an X99 with a 6950X @4.4GHz to a X299 with a 10940X @4.7GHz (but I've been at 4K for quite a few years).

You're playing at 3440 x 1440 like I am, so you're probably not going to see a huge difference from a CPU upgrade, with the 3080.  You can always do it later, but I wouldn't worry about it too much.  At that resolution you're almost always going to be leveraging the GPU a lot more than the CPU, unless the game is very CPU bound.  Even then, I don't think the difference between a 7000-series & 10000-series will be "huge" in your case.
I saw more of a performance increase from a simple CPU speed bump than anything else so far, the 3080 sure does like to eat as much power as you can give it CPU throughput & such wise.  
Another thing to seriously think about is getting faster RAM maybe as well?  If you're going to upgrade CPU especially, I would try to find RAM that has a history of working well with your motherboard, and runs at at least 3600MHz.  Several review Youtubers have shown that there is a noticeable differenc between sub-3200MHz RAM speed performance, and going to 3200-3600MHz RAM, on all the newer chipsets.  It's not as big of a difference as it can be on AMD, but it's still noticeable, and in some games can be as much as a 5-10% increase in FPS.

Que?  Spanish for 'what'?
 
It's amazing how so many people can afford to purchase a 3080 or 3090 but can't spell queue.  What do they do for a living?

It was just an observation.  An observation of something which has happened frequently recently.
 
I didn't come here for that purpose.  I came here to read the thread.  It's the only thing I found interesting in this thread.  Otherwise I would have come and left without saying anything, just like I do for all of the other threads I view which I find uninteresting.
 
It seemed like this thread was pretty much dead, so it didn't seem like my off-topic comment would impede any discussion.

Yeah, the RAM thing has crossed my mind a couple of times. With all the Black Friday deals going on I'm going to check around this month and see what's a good deal on sale that's faster. At this point I won't have the 3080 till December at the earliest so I can put some money towards some new RAM. Any suggestions. I've always stuck with Corsair, but open to other's if the performance is there.

G.Skill is typically considered top notch.  Most of the brands nowadays use the same stuff, there's only 3 actual chiplet makers for the RAM chips that are really in the game so to speak, SK Hynix, Samsung & Micron.  Samsung B-Die is typically considered the top tier, because it usually overclocks the best.
The majority of G.Skill's better (tighter timing higher speed) kits are Samsung B-Die, though you can google "Samsung B-Die checker" and check the model # of the RAM you want before hand & see if it is or is not.  One thing to keep in mind if you do get Samsung B-die chips, they don't like running on the hotter side, anything above ~40C and they will typically overclock less... assuming you want to OC your RAM at all past XMP.
For the X299 Dark, it ain't the fastest, or the cheapest, but it is a solid option: https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820232492 is the exact same RAM I have, and I'm running mine at 4000MHz CL17 1.42V with no issues... but we are on different platforms.  It is on the QVL in a 64GB version, but that's 8 sticks, this one is 4 sticks, everything else is the same so it should "just work" & all you have to do is enable XMP & fly.

F4-4000C17Q-32GVKB is a little cheaper for a 4000 C17 4x8GB kit.

Hey Folks, love the ideas you guys have given me. I went ahead and picked up some new RAM as it was on a good price point for 32GB.

Has good reviews from most customers and I verified works with x299 Dark.

I didn't end up getting that and decided to stay with my 7920x for now. The new RAM is doing awesome, and right now I'm just waiting for a 3080 or an RX 6800XT to grab and my cpu will pretty much be where I want it to be for the next year or so. However I'm sure I'll get that itch sooner or later to do a new build.
