i5 2500k to a i7 3770k upgrade to improve FPS lows?

Hi all,

Just a quick one as the header reads.
Currently I have my 2500k Oc'ed to 4.4ghz which paired with my Gtx1070 runs pretty smoothly @ 1440p. The only let down is the occasional FPS lows so I was wondering if there would be a noticeable improvement with 3770k.

Reason is I'm looking to upgrade but if I could possibly hold of for another year and just improve my current system I would be more than happy.

A second hand 3770k I can pick up for around £180 which is far cheaper than the MB, Ram and CPU upgrade I was originally looking at to get a definite upgrade.

Basic specs as follows :-

Asrock extreme4 z77 ,
I5 2500k (oc 4.4).
Nvidia Gtx 1070
16gig 2400 DDR3.
256gig Samsung Evo SSD,
480gig Sandisk SSD.
1tb 7200rpm HD.
Windows 10.
27" 1440p/144hz monitor.

Any information / comparable data would be much appreciated.

Regards,

Lee.

BF4 ran beautifully on my i7 3770K, loads across 8 threads was about 30-35%.

On one side you're able to stay within the same socket and get somewhat better performance for longer. But on the other side, i7 3770K are still near MSRP price unless you scourge around on eBay (of which are loaded with shady scammers lately).

So hold off until you have enough money for a 7800X or a Ryzen build.

According to this:
http://www.tomshardware.com/reviews/cpu-hierarchy,4312.html
The 3770K is only one tier higher game performance-wise than the 2500K. You need at least two or more tiers to be a noticeable upgrade. Key word here is noticeable.
I am in the same boat you are in, with the 2500K, But I am going to wait for something better than a ~lateral upgrade.

Battlefield One - the latest one released ... so confusing lol.

https://forums.anandtech.com/threads/battlefield-1-beta-cpu-scaling-performance.2485172/

This shows a 19 fps difference between the i5-2500k and the i7-2600k.

This should be similar going to an i7-3770k.

The increase appears to be due to hyperthreading not frequency.

Thanks for the replies all.

This is in the likes of Skyrim, Fallout 4, Deus ex:Mankind divided, Insurgency, Dying light, Farcry 3, Arma 3.... are a few of the games I'm playing currently.

I'm not at my pc currently. I have cpuz but if any one could recommend better monitoring software for CPU and GPU it would be much appreciated.

Forgot to add, I always insure my bios / graphics drivers etc are all up to date and I've had the same kind of FPS drops through out. I feel I've noticed them more however since going up to 1440p from 1080p.

Thanks again.

if they happened when you increased resolution, that's almost always graphics card, not cpu. 1070 is strong, but at 1440 it's not quite enough for really high frame rates, certainly not enough to max out your refresh rates. I've got 780tis(sli), about a 1080 or so in terms of pascal, my refresh rates aren't anything to gloat over, some of that is lack of sli support, but reality is, you would need a 1080ti to get really great refresh rates at 1440.

Cheers chaps,

I see what your saying Dudmont but it's more reducing the drop rather than hitting the peak if you know what I mean.
Going from 140 say (Gsynced) and dropping to 55 just seems a bit excessive and as punchy as 2500k still is for an old bean the drop seems more apparent with that chip than with similar or slightly higher rates CPU's.
I'm almost making it sound like this is in every game fallout 4, Deus ex and Farcry 3 are main culprits.
I think I've read in the past some where that certain chips can have this effect. The 7700k would actually appear to be one of them from many posts I've read. Saying that, every ones hardware is different so may not be as compatible as some one elses.

Maybe I am expecting too much from my 1070 and was just worried that my 2500k may be bottlenecking in a game or two.

Thanks all for the replies, I'll keep an eye out for some software to which I may be able to confirm what I'm thinking in which I can then save for my future system upgrade instead.

Cheers again,

Lee

Keep in mind, the increase from 1080 to 1440 requires 2x the pixels rendered. A frame rate of upper 40s to mid 50s is perfectly reasonable for the power of that card. When things get heavy, it will drop to a lower level yet. All of which will be visible.
I'm still curious about CPU usage numbers, if we see all threads running at high rates(80%+) during gaming, then a CPU upgrade would definitely be sensible.

I did notice Dudmont that Deus ex would run the CPU up to 100% most the time and I would average 45 to 90 FPS. 6 years later and the 2500k still rocks pretty well.
