yet another 8350 upgrade advice

[farmerboy-86]

so title says i have a 8350 @4.8ghz (outdated sig) with a r9 fury x on custom loop

i have a racing simulator and the system handles most games maxed on my 21.9 34" lg panel 2560 x 1080 75Hz

but i play the odd rpg witcher 3 and i keep getting fps drops into low 50's

i assume the panel takes a little more than a 1920 x 1080 to run at 75 fps

my gpu sits @ 100% while cpu is around 66% ish title dependent

so is my cpu holding me back??

i know its a old cpu just wondering if skylake will help with the fps spikes?

i intend to stream as well as game hence my idea to jump ship to intel

considering i7 6700k

also will my gpu need changing to max games or purely the cpu holding me back?

I think generally you'll get a better experience with an i7 over your FX8350, mainly for the minimum frames.
But where you're pegged 100% GPU usage, a CPU's not really going to help.

There's not a massive deal to buy GPU wise unless you go Nvidia, but you're already at the end of the scale on what you should be pairing your CPU with.

Cpu at 66% means it's not being fully utilised, if your gpu is at 100% load as you say in most titles then it's definitely not a cpu bottleneck. You would be seeing the results reversed, ie gpu holding back waiting for instructions from the cpu.

Edit: Martini types faster than me

A CPU doesn't need to be fully utilised to create a bottleneck, it's about the cores themselves.
Where OP mentions FPS spikes, depending if those are CPU bottlenecked scenarios, then yes. But it's not going to make a Fury X better than it is.

Yes it depends on the ipc, floating point speed and integer speed of the architecture but in this instance it's clearly not a cpu bottleneck, if it was the case you would expect to see spikes on the cpu usage graph.

No, I'm on about the number 66%. 66% CPU usage could be a bottleneck, it depends on how that load is distributed, but with 66% usage on an 8 core, you could imagine some of those cores being maxed out. Those spikes he mentions for example could be cases where he's indeed got a bottleneck.

Like I say, for consistency, an i7's going to be better than an FX83, but that's a given, I don't think a Fury X is up to maxing Witcher 3 at 2560x1080 anyway, but an FX83's not a great combination to be using with a Fury X.

I'd upgrade them both money permitting, or leave it as it is.

EDIT : Ideally you'd just want an hours worth of gameplay break down on GPU usage to determine a CPU bottleneck, if that's spiking all over the place then you've got a bottleneck, I like to see a nice solid 99% line.

Thanks for the info guys I know the 8350 is showing it's age a upgrade has been on the cards for a long while
Like I say apart from project cars I can max all sim racers I play easy but there not to taxing on graphics I racing etc

But when I play other games I do get fps drop in heavy loaded areas a lot of Npc's or a town say in wit her 3

My budget is £1500 so I'm thinking i7 6700k and gtx 1080 and water block for 1080 as I'm on a custom loop

So need mobo ram cpu and a 1080 £1500 is so able I guess

If you're running TW3 at 2560x1080 ultra settings, those are totally normally framerates for a Fury X and not indicative of a CPU bottleneck.

As said though, the problem is by upgrading to a GTX1070, then the FX8350 becomes the bottleneck.

Despite the FX8350 showing its age, Witcher 3 is generally fairly CPU friendly though, so you can upgrade to a GTX1070 now and leave the system overhaul a bit longer if required.

The minimum frames would improve in this particular title.

 

[farmerboy-86]

Well I bit the bullet and brought a i7 6700k
Gtx 1080
16gb ddr4
And the Asus maximus formula 8

And boy it seems night and day over my 8350

Thanks all for advice

Good upgrade farmerboy, I think you had the FX a couple of years pushed hard similar setup to me. As the clever boyos answered earlier the combo you had was the best you will get other than replacing the hardware completely.

I will wait for the zen release and a good extra 6 months after till I start preparing for the next build. Not fussed which camp it is with just whatever is best for the £££.
