Should i upgrade or not?

[Gregkar13]

Hi all,
I am in bit of a dillema, i am into simracing, with high end equipment, and recently got into VR,
my current PC specs are:
i5-3570(NOT K) @4.2GHz
Asus Z77-A
Msi 1070 armor
16Gb Vengeance @1600+mhz
i have a problem using the rift in the simulators i am using (iracing, Assetto Corsa, Pcars 2), if i increase the settings that affect CPU, then my frames drop, ASW kicks in etc..
I am about to upgrade to:
i7-8700k
Asus Z370-A prime
16gb DDR4 G.skill @3200mhz

my only doubt is: WHY steam VR show my pc 100% perfect for VR and still i have those issues?
should i do the upgrade or not?

This happens when your pc have a lot of other things to do:
antivirus
other programs etc.
Steam does not run benchmark, just checks specs vs preset dictionary.
I think It would run much better on steamOS
Also I think its missleading 100% is 90 fps at low settings

well, the min requirments is an I5 4590, so your not quite there yet. But the i5 3570 is not bad CPU by any stretch.

On the upgrade, well you obviously feel your not hitting the performance you want, and that is the main reason to upgrade. So you've chosen the absolute best gaming CPU available. You could drop that to an I5 8600k and it would still be awesome, but save you a couple of quid that you could put to another piece of hardware. The 8600k is 6c/6t but that is plenty. For more resources and if you have the extra few quid go for the 8700k (6c/12t). You won't be disappointing with either chip.

forgot to mention that i am pushing vr quite a bit, i am using 1.5-1.8 supersampling in some simulators. don't know if this requires more CPU power, have almost never tried stock 1.0 superspampling

Well, thats more of a GPU thing, but having a quality CPU will certainly help.

With your current CPU, you have the min requirement. So if you upgrade CPU (mobo, ram etc) and use the 1070 you will certainly see a huge performance increase, not necessarily in FPS, but more so, more available resrouces/threads which will help your gaming experience.

The 8600k will do fine for your needs. The 8700k will just give you more headroom. Like I said if you have the cash the 8700k would be what I would want. But the 8600k will be perfect for your needs too.

I've a Ryzen 1600x 6c/12t CPU. I love how it can handle anything I can throw at it. Having plenty of resources means I can run anything on it (within reason, as I'm limited by my GPU), but the CPU is very capable.

If I were you, i'd be taking the 8700k and not worrying about anything other than a GPU upgrade further down the line to maintain a great gaming system.

Thanks i will check, but honestly i don't run many programs on the background, other than steam, google drive etc.. and as antivirus i use microsft essentials...

yeah i struggled a lot choosing between i5-8600k and i7-8700k, but i need to get something that i won't be upgrading anytime soon, plus i use OBS software for live streaming, adobe premiere etc.. so i think i7 is the way to go

 

[keith12]

yup for sure. You seem to be a power user as such, so if you are doing CPU demanding tasks the 6c/12t 8700k is the way to go.

Good luck

well, the min requirments is an I5 4590, so your not quite there yet. But the i5 3570 is not bad CPU by any stretch.

The Core i5-3570 at 4.2 GHz should perform slightly better than the Core i5-4590.

are you sure? my teammate has an 4590 & the same gpu as me plus the rift, and he absolutely destroys me...

i think you're missing the point. You cannot OC the I5 3570 it's a non 'k' CPU, so how would you get it to 4.2ghz!? With a BCLK OC. That' not gonna happen.

that answer is incorrect. You cannot OC your CPU. It's not a 'k' (unlocked CPU)

That is not correct. The Core i5-3570 can be multiplier overclocked. Here's how it works on the Core i5-2500 as compared to the Core i5-2500K, but it applies the same way to the Core i5-3570:

Your talking about the Turbo Multiplier as opposed to a CPU multiplier. Regardless, the point here is that despite a moderate OC (whether achieved with a Turbo Boost multi increase or BCLK, or not) won't make much difference to the OP's issue.

From what I can see, the Turbo Multi resets each time the PC starts. This maybe mobo dependent. It's not an ideal way to OC. Also it appears that the turbo multi OC only brings all cores to the max turbo, 38, not 42. I may be wrong on that, I haven't tried it in a long time.

No, I'm not talking about Turbo Boost. As you can see from the slide, the 2500 at stock turbos to a maximum of 3.7 GHz. But you can overclock it to as much as 4.1 GHz. Similarly, the 3570 at stock turbos to a maximum of 3.8 GHz, but OP has overclocked it to 4.2 GHz.

None of that resets. I have had my Core i5-3450 overclocked to 3.9 GHz for 5 years.

ah, okay. I've misunderstood the way it works. Thanks for pointing that out. I thought the 4 bin OC was form stock, and not the max turbo.

edit: ah i see now. The 4.1 is for a single core. For all cores its less 3.9?

Yes, the overclock is just 0.4 GHz on top of what it would normally turbo boost to.

I am on 4.2GHZ on a non K 3570, using ASUS motherboard's Auto Tuning in AI Suite II software. hope that helps.
