3080 with a 2700k @4.9ghz

Am I right in thinking that if I only game at higher resolutions like 4k my CPU won't bottleneck?

While here is the 3080 about 50% faster than my 1080 ti?

Anything from AMD coming soon?

Thanks
 
It depends on the title, but yes, it will bottleneck to some extent. You will still see a huge increase in performance though and of course the new RT support. You just won't hit the high scores that others post under benchmarks.

BTW. I'm still using a 3770k @ 4.5Ghz in my most used PC with a 1440p panel. I have a 3080 on order to replace my 1080Ti FTW3.

Depends largely on what games you want to play as to whether you will be CPU bottlenecked or not, might want to take a look at this...

I thought I was pushing it thinking about using a 3080 with a 5930K :) (I still have a 2600k in my work PC by the way, fantastic processor range)

The resolution you game at will be the crucial factor - If you're gaming at 4K then no you're not going to be bottlenecked much as the GPU will still be the limiting factor. It's only at 1080p and wanting stupid-high frame rates that older processors become an 'issue'. Still, 4.9Ghz is a fantastic overclock and will go some way to helping out.

A handful of games do benefit form more cores/ threads though, so a 2700k will start showing its age there, and more games will start being more multi threaded with the new consoles. I hope so anyway.
 
I had a 2700K at 5Ghz with a 2080Ti until a few months ago. It was quite fine (for example, I mostly played Doom Eternal at 4K and 60fp in Ultranightmare or Black Mesa at maximum settings) but certainly a bottleneck for the card in some games. In a few titles the frames per second went up quite a lot with the new CPU, to be honest.

P.D: I think that the 2700K is still a great great CPU for everyday tasks :). I am not getting rid of it.
 
CPU bottlenecks tend to come down to one question, which is what is your target frame rate. If you were aiming for say 120hz @ 1440p then yes that CPU would be a big bottleneck. If you're using 4k and your more likely target frame rate is about 60fps then it will hold up in a lot of games pretty well, but probably fair pretty badly in CPU intensive games like PUBG, FS2020 and things like that, games with large player counts, large battles or complex simulation. But that's right now, the future use of a CPU that old will rapidly become a problem so if you don't upgrade now you will have to soon. I still have a 2700k @4.9Ghz in an old backup rig, it's no slouch and CPU improvement over the years has been slow, as has been rising demands from games so depsite being 8 gens old it's actually not all that bad at that speed.

Thank you!

I only game in VR and age of empires and total war games
 
I've looked into this quite extensively recently and as many have already said, unless you're after high frame rates (Above 60fps) at 1080p or even 1440p, the 2600k still isn't holding you back that much, with the gpu still being most of the time the Bottle neck. You will however, gain minimum fps and more smoothness in lots of titles.

That's especially true for Cpu intensive games which NEED the extra cores, like assassins creed games, civilisation, warhammer total war and anno which will, however, see massive gains in fps, as the 2600k won't be capable of hitting 60fps at any res/settings. Even low. Even at 4k.

Assassins creed for example, STILL won't even run at a constant 60fps lock on a 3080 at 4k with modern cpus.
The cpu is a bottleneck, so it doesn't matter if you paired it with a 5080ti in 2023 - the cpu still will not be able to deliver 60fps.

Ive got the same CPU and overclock and have updraded my 1080Ti to 3080. Most games ive played are fine but im finding the FPS drop significatnly (>45fps) when driving on a modded GTA V and G-Sync starts to chug. Im thinking it may be a CPU issue.

This is 3440x1440p.
 
No idea why you would spend so much on a gpu only to pair it with an archaic cpu :confused:

Sure you'll see improvement, but you won't get the best out of your card.
 
A 4.9Ghz turd is still a turd. Get that relic of the past on a keychain, or in a photo frame, it was a great CPU years ago.

I'd recommend getting a Zen3 or Rocket Lake (11900k) when they release, whichever is fastest in games. Both will be amazing.
 
The 2600k also only supports pcie 2.0 I believe, so even if you did manage to clock your cpu high enough to feed more frames to the gpu, that would also be another bottleneck.

For total war you really should look at a newer CPU, unless we're talking Medieval II or there abouts. The campaign turn times will be a lot nicer for a start.

This!

I can understand a new GPU for VR, but id try and get a more rounded system, maybe get a 3070 or a second hand 2080 and grab an 8-9/10 series intel or a Ryzen?
 
When I went from an i5 2500 to a 9700, I believe that I had a frame rate improvement of around 50%.
However, I was only running my 2500 @3.8ghz. Given that the OP is running roughly 25% faster, I’m not convinced that his frame rate is suddenly going to rocket.

My experience was that the real benefit was less from the CPU and more from the rest of the system, Ie motherboard, RAM and NVME SSD. Also, a 2600 can only run DDR3. So personally, I thought the biggest improvements were in faster load times, massively reduced stutter and similar in games.
