Default 2500k or 3770?

Hey Folks,

Just wondering whether it's worth swapping over my cpu. I've currently got a 2500k comfortably sitting at 4.5Ghz but have got a 3770 (non k) I can swap in as well.

I mostly play battlefield 1 and dota 2. Dota 2 is fine but Battlefield 1 uses 100% of the CPU all the time.

I've got a 7950 in it at the moment which runs everything fine. Just wondering whether i'm likely to see a bit lower cpu usage with the i7 over the i5 at all?

Not in a financial position to get myself a new GPU at this stage unfortunately.

Cheers for advice,

Kym

Why not test for yourself?

It's impossible to give you a definitive answer for all games... However the overclocked i5 will perform best in games that aren't well optimised for multiple threads where as the i7 will do the opposite, performing worse in poorly optimised games (due to lower clock speed) and best in well optimised.

If I were you I would keep the i5 and sell the i7. Hell, sell them both and purchase an overclockable i7 😁

most games at the moment unless they're proper dx12 games can't use the hyper threading offered by the i7 cpu, so there isn't alot of reason's to upgrade to it

really your 2500k will be ok for atleast another generation or two

An overclocked 2500k is still pretty beastly, I'd keep it personally.

3770, which you can mildly overclock by increasing the multi.

Try different configurations in 3DMark Search to gauge the differences.

Having just gone from a 3770k to a 6800k the difference in performance is not much though i am much happier with the CPU usage on the 6800k compared to the 3770k.

In BF1 with an 980 Ti, on the 3770k I was seeing CPU sit at mostly 80-95% usage pretty much the whole time in game.
when going to the 6800k with the same GPU, I was seeing cpu max out at 80% but most of the time float around 60% (keep in mind this is me glancing at the rainmeter setup while playing)

Frame rate between the 2 CPU's on DX11 was about the same with the same GPU.

i did document some benches in my upgrade progress from late last year. Here is the link if you want to have a look. Hope this helps.

Thanks guys. Beginning to think that bf1 optimisation is for the newer cpus even though it doesn't seem to affect frames and in game performance.
I've been looking on the forums to see if I can pick up a 2600 or 2700k for cheap and get it to the same clocks as the 2500k as that should be a nice little upgrade.

Thanks for all the food for thought and input everyone!

don't bother, I reckon the differences would be minimal. Hold onto your pennies.

What's your RAM usage and what res are you running? My mate has a 2600 with 8GB RAM and GTX 1080 pushing 1440p, he's got loads of microstutter, barely playable and RAM usage is around 90%.

Not even 1080p my monitors are old and I limit fps to 60. I've only got it paired with a 7950 too.
I do have 16gb ram at 2133 so shouldn't ever have an issue with that! I have noticed ram. Usage was around 80% till I upgraded recently.

2500k's can OC like crazy so I'd say it'll last you a fair while. You won't notice much of a difference.

Why not sell one of the CPUs and use the money for i7 3770k than sell the other CPU.

Than you have the best of both world. I7 3770k is a biggish (15%) upgrade for a 1155.

Is it still a big upgrade if my 2500k is sitting at 4.5? y understanding is the 3570k and 3770k get a lot hotter and generally OC at a lower speed to stay stable than the 25, 26 and 2700k? Please correct me if I'm wrong.
I think I'm steering more towards getting a 1070/80 with my current setup to see me through for awhile and look at getting a couple of new monitors too.
Seems the 3770 may be worth a few bucks!

You have a good cooler in the Hyper 212 so I don't see why you couldn't get at least 4.2GHz stable (dependent on your chip, 4.4 to 4.6GHz is pretty standard on those chips and they'll take 1.45V according to a quick Google search in Tom's Hardware forums). 4.4 should be achievable at under 1.35V. Once you have a speed you're happy with, reduce the Vcore until the OC becomes unstable, once it does increase the Vcore by increments of say 0.01V until you're stable (being that Vcore directly correlates to heat at the top end and stability at the lower end).

Heaps of good OC help on YouTube if youre not up to speed, remember YMMV.

I think using the sale proceeds to get a new gpu and monitors is a great idea.
