[SOLVED] Upgrade from i7-4770

As in the title, I'm looking to buy a new graphics card (around 2080 performance) and I'm wondering if my old i7-4770 will be bottlenecking it a lot and should be replaced at the same time?
 
Solution
Depends on the game, in modern CPU heavy titles say BF5 or AC Odyssey yes you would likely see some bottlenecking using something like a 2070 super or 2080. In older or less CPU heavy titles not so much. Resolution will also affect CPU usage, at 1080p in those games I would expect to see a lot of CPU bottlenecking at 1440p or higher not so much.

Depending on your current GPU you should still see a good gain in performance in the majority of games even with that 4770. I would upgrade the GPU first see how the games you play perform then decide if you need to upgrade the CPU now or wait a while.

Great point, thank you. I am looking into the future, titles such as Cuberpunk 2077 for example, I play a bit of open world games which tend to be CPU heavy. Never thought of the resolution being a factor, and I am indeed looking at 1440p with my new GPU.
The one I'm currently using is GTX770 2GB, so in the current setup it's GPU bottlenecking CPU if anything.

Oh yeah something like a 2070 super will be a LARGE upgrade over a 770 even with that CPU.

Rumors for the min requirements for cyberpunk are showing a 6700k as min CPU. I'm sure your 4770 will run it but no idea how well. So yeah upgrading for cyberpunk might be a good idea. Note that any meaningful cpu upgrade will require you to get a new motherboard, DDR4 RAM, as well as the CPU.

Yeah a higher resolution will put more load on the GPU, lowering framerate thus taking load off of the CPU. Its a bit counter intuitive but yes increasing resolution typically lowers CPU usage and increases GPU usage in games.

My stock approach to this perennial question:

Some games are graphics limited like fast action shooters.
Others are cpu core speed limited like strategy, sims, and mmo.
Multiplayer tends to like many threads.

You need to find out which.
------------------------------------------------------------
To help clarify your CPU/GPU options, run these two tests:

a) Run YOUR games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.

b) Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
This will simulate what a lack of cpu power will do.
Conversely what a 30% improvement in core speed might do.

You should also experiment with removing one or more cores/threads. You can do this in the windows msconfig boot advanced options option.
You will need to reboot for the change to take effect. Set the number of threads to less than you have.
This will tell you how sensitive your games are to the benefits of many threads.
If you see little difference, your game does not need all the threads you have.



It is possible that both tests are positive, indicating that you have a well balanced system,
and both cpu and gpu need to be upgraded to get better gaming FPS.

Geofelt, I know that in the current setup it's GPU that's bottlenecking CPU, but when the GPU changes this dynamic will change too. Your suggestion would only make sense to try after the GPU upgrade, am I right?

Never thought of the resolution being a factor, and I am indeed looking at 1440p with my new GPU.

Oh, it most definitely is. Resolution, and, to some extent, refresh rate, though refresh rate tends to be a factor of both GPU and CPU.

For an (absurd) example: You'll need FAR less GPU horsepower to run a specific game at max details at 720p, than you would to run the same game at the same frame rates at 4K resolution. Far more pixels to push. That's all on the GPU.

Why the 1440P monitor?
If you are looking for an increase in size or resolution, I am all for doing that first.
You will then have a better idea of what graphics you may need.

Next easiest is the graphics card. Whatever you get will be easily transported to a new build.
You may well find that you are ok with your processor, at least for a while.
There is always new stuff that is around the corner.

Almost all CPU's and motherboards newer than intel 4th gen require DDR4 RAM. DDR3 physically wont fit into most newer motherboards.
I think this has now swayed my decision. To fully utilize a new GPU I'd have to change pretty much all the components except for my case. In light of this I've bought a 1070 for £250 on a sale and will stick to 1080p for now and will just upgrade a GPU for now and see what consoles come out next year. If new Xbox is capable of actual 4k 60fps that'll do me fine.

Have you already purchased the 1070? If so, can you return it? The 1660 Super goes for less money, consumes less power, and performs about the same as the 1070.

I've looked at 1660, but given the current discount on 1070 it still worked out cheaper on the storefronts I looked at. So a bit more performance is a plus, I have PSU with surplus of energy anyway and the price worked about £20 cheaper.
