1080Ti SLI on i7 4770K

Sekrab · 28 Mar 2017 at 18:41

Hello folks

I've just upgraded and am currently running 1080Ti SLI with an Acer Predator x34A @ 3440x1440

I'm not at all disappointed with the performance, however as some games are more CPU-dependent than others I'm not always hitting as higher frames as I'd like. Is it worth my upgrading from my current i7 4770K to a newer cpu & motherboard? Will I see any benefit? Do I have a performance bottleneck with this combination?

are you overclocking the 4770k ?

Sorry, a good question.

It was part of an Overclockers bundle, came pre-overclocked at 4.2 I think.

I've just gone from a 4770k @4.5ghz to a 7700k @5ghz & I'm quite impressed at the boost its given.
Even at stock (4.2) the 7700k is a nice little increase.

Before seeing it in the flesh I was sceptical whether it would be worth it, but if you have a money then I say go for it.
Selling off your current setup helps offset the cost as well.

He'd be mad to pay for a whole platform for four cores @ 4k. If you are planning on changing CPU now you'd ideally want at least 6 cores.

Like I said it worked for me, I was going to wait for 6 or 8 core but decided you could be waiting forever for the right time.

Overall after selling off old setup it's cost me about £500 to go from a 4770k, Z87 motherboard 16gb DDR3 980ti to 7700k, Z270E-Gaming, 16gb DDR4 & 1080ti

It worked for you in the sense that you saw an increase in performance. The difference between the 4770k and 7700k at 4k is going to be minimal at best. Did you run both CPUs with the same GPU?

Is the overclock still active though ?

Sekrab · 28 Mar 2017 at 20:21

Yes it is, good shout though as it does have a habit of reverting to defaults!

IvanDobskey · 29 Mar 2017 at 07:22

A 4770k is still a pretty killer cpu.

Keep it for now.

Sekrab · 29 Mar 2017 at 08:22

Looking at this and other similar threads that seems to be the consensus, I'll stay put for now. Thanks for the input though.

IvanDobskey · 29 Mar 2017 at 08:48

I think until games start using more than 8 threads, an i7 2600k or better will be good for gaming.

Definitely overclock if you haven't already though.

wedrum · 29 Mar 2017 at 08:51

you should be able to get the overclock to 4.5ghz - 4.7ghz cooler depending.

Glanza · 29 Mar 2017 at 08:59

Even with 1080ti sli are you still not hitting 100fps in games? anything higher isn't really needed with the monitor you have.

orbitalwalsh · 29 Mar 2017 at 09:16

went from an i7 860 to a i5 7600k and noticed 30fps jump with 980 ti/1080 haha, prob a Second Gen and pushing 3rd Gen would see an improvement but i'd stick to what you got.

Maybe get a bit adventurous and delid/ manually overclock it yourself

Unlikely on the 4770k. Most would do 4.4Ghz with only the best doing 4.5+. Mine tops out at 4.3Ghz.

I had a poor 4770k which would only do 4.3Ghz, I ended up selling it for a 4970K. I lost out on the silicone lottery.

I would certianly not suggest upgrading the CPU at this time and when you do (I would suggest next year) then you really want to be looking at a 6-core plus.

I have not seen any difference in CPU's from the 4770K to the 7700K with the same GPU and RAM at same speeds (bearing in mind the DDR3 & DDR4 difference). I would suggest anyone seeing difference either had previous issues, upgrade the GPU at same time so can't say what impact the CPU has or is lying in honesty.

But they have to make them selves feel better somehow. A little white lie didn't hurt anyone ;-)

From the benchmarks i've seen there is around a 20-25% in single core performance and 20% in multi core. That's a good increase and if you add on top RAM & MB upgrades then surely a nice improvement?
