I would never upgrade my GPU without an associated CPU upgrade.  You will always be CPU limited.

I’m usually only ever able to upgrade one thing at a time. Right now I’m GPU limited with my 1080ti at 2K. I know I’d be CPU limited if I upgraded to a 3080 with my 9700k, but I’m sure I’d still be able to achieve at least 40-45fps with complex addons which I would be happy with. I do have my 9700k overclocked to run at 5Ghz though.

I run an i9 10850K at 5.1ghz with a 3090 in 4k, aiming to maintain 50fps.  In extremely complex weather the GPU can still max out, dropping to render scale 95 tends to keep fps solid at 50fps throughout with little noticeable image deterioration.

So if you guys are saying a 3080ti will limit your CPU, what model CPU do you guys recommend that will keep up? (taking notes for my next system)

Hi all 

Just dropped in a 3080 ti from a 1080 ti, cpu is an i7 8700k, 64 gig ram was not sure what to expect,fps at my local airport in Australia went from 35 to 50-55 at 4k, if only I could afford a 3090 lol, might be of interest to any body in the same boat who is curious 

I had a similar experience.  Went from a 1070 at 35 fps to a 3080 at  55 fps.

I used the link provided by Maladoror, thanks. It tells me my 1080Ti is the weaker component compared to my i7-8086K running at 5.0Ghz. I run at 3840*2160 @ 30Hz natively.

Given the age of the 1080Ti it doesn’t surprise me. I’d always been put off buying a 2000 series card because it would mean dropping to 8Gb VRAM from the 11 the 1080Ti has.

But now that the 3080Ti has 12Gb that problem disappears. My only question is will the 3080Ti accept the same connections as the 1080Ti? The size seems okay and I have a 750W gold power supply.

I went from 1080ti strix to 3090 strix and had to add extra 8 pin cable. Don't know about 3080ti. Also I think, it depends on model. Some have 3x8 pin and some 2x8 pin.

I would double check the Power-Consumption with a PSU Calculator so you don't run into any unexpected under-power scenerio. e.g. https://www.bequiet.com/en/psucalculator

Intel Core i9-9900K is too weak for NVIDIA GeForce RTX 3080 on 2560 × 1440 pixels screen resolution for Processor Intense Tasks.

This configuration has 14.5% of processor bottleneck .

When playing games your graphic card won't perform on maximum possible performances (won't be utilized to the maximum), because you processor won't process and deliver data fast enough. This theoretically means that utilization of you processor will be on maximum and the potencial of graphic card will not be completely used.

 

Also, this is interesting, not sure how accurate... https://pc-builds.com/compare/cpu/0RM/1cn/?game=1Z

I just checked my order and I have a Corsair RM850x 80 PLUS Gold 850W PSU. So I'm sure that will be fine. Checking that calculator confirms as much.

Regarding the connections it seems to need 2x 8 pin connectors. If anyone knows what the 1080Ti needs that would be helpful.

Pretty sure it does not matter, because most PSUs have 6+2 pin connectors for PCI-E. So, even if your 1080ti uses "only" two 6 pin connectors, it should work, as the +2 pins are available on the cable (just not used now). Other than that, without knowing the exact model of your 1080ti, nobody can tell you what connections it uses...

My factory overclocked 1080Ti GPUs use two 8-pin connectors, as does my 2080Ti and my 3090.  Some of the overclocked 3090s use three 8-pin connectors.  I think I remember some of the 1080Ti boards using one 8-pin and one 6-pin connector.

I have not done much testing yet but I did notice slight stuttering when I look out the side windows but alleviated with vsync and locking to 30 fps, I have some more playing around to do

I believe the offscreen scenery cheche (or whatever the settings is called) is supposed to help with that also.

Still think the 1080ti is a superb card, never had problems in 2k ultra with my i9 11900k, however my next card could be the 3080ti, the prices are getting sweeter, maybe in May could drop to $1100 or 1200?
