Hey guys, I was hoping to get some opinions on whether or not it would be worth it to upgrade from my i7-4790s to an i7-4790k.

I can get a used 4790k for about $150 from my local second hand websites but currently I have a 4790s and an EVGA z87 classified motherboard. So the motherboard is capable of high end overclocking but would it be a significant upgrade over the 4790s? The reason I want to upgrade is that I was worried that my GTX 980 TI is being bottle-necked in some games. For example, my brother has a 1070ti and he's constantly over 120 fps in fortnite during bus drops when mines dips to like 80 and on average even on the ground he's about 50-60 fps higher than I get. The difference is smaller in Ring of Elysium but its still significant. When I go play on his PC I notice a difference in both games.
 
Will an upgrade from a 4790k from a 4790s be worth the upgrade of $150 in terms of fps and game performance? Or should I just wait for the new ryzen series.
 
Thanks for the advice.

What is your CPU utilization when gaming ?
 
What Monitor resolution 1080, 1440, 4K ?
 
His 1070Ti @ 120 fps VS  your 980Ti @ 80 fps ---> what MB, CPU, RAM & OS & Nvidia driver difference between the builds ?
 
I'd find some reviews to see if the FPS will increase in the games you play @ the resolution you play if your CPU would OC better = K version

Hey, thanks for the response
 
My build is as follows:
i7-4790s @3.2 GHz
16 GB dual channel ddr3 @ 1867 MHz
EVGA z87 classified motherboard
EVGA GTX 980 TI SC+ ACX 2.0 GPU
Latest NVIDIA drivers downloaded from website
Windows 10 with no bloatware or windows store/apps
 
His build is as follows:
Ryzen 7 1700x
Gigabyte AX3709 Gaming-k3
16 GB dual channel ddr4 @ 3000 MHz
Gigabyte Aorus GTX 1070 ti (3 fan card)
Latest NVIDIA drivers (i installed them myself from same website)
Same windows 10 install as mine
 
I know his build is better overall than mine so it should perform better (that was our goal) but my concern is how drastic the fps difference in game is. I feel like it should be a bit closer since his gpu or cpu is not overclocked and the benchmarks are not that far apart for individual components. So this leads me to believe something in my system is bottle necking and I have no idea what it could be

His system platform is overall faster. Just the memory bandwidth between the DDR3 and 4 and his boost in memory speed
It is all about keeping the GPU feed

But can that really make thay huge of a difference in fps?

Is my processor the bottleneck or is it my Ram?

During gaming my processor generally sits at 50% usage but it runs at the max turbo of 3.6 ghz

Use an actual benchmark program, plenty of free ones, heaven, superposition ect then you can start to see the differences. Run super position at both 1080 and 4k to see the load differences
1080 will be CPU dependent 4k will be GPU

Well being as the only real benefit will be overclocking potential, which is always a gamble anyway, it almost hardly seems worth it. However if you can pickup a 4790k at a decent price and sell your old 4790 for a decent chunk of money, and maybe only be out $20-30, it might be worth it. Honestly though in a single GPU system, I know the 4790S isn't bottlenecking a single 980 Ti that bad(If at all). I've ran 970's, 980 Ti's, and now 1080's with my 4790K. Even at default CPU speeds, the performance impact of going from base clocks to say 4.6Ghz isn't that massive(at least at 2560x1440). Like Cool GTX asked earlier in this thread, it's very helpful to know what resolution & refresh rate you are after.

Re: CPU upgrade advice 2019/01/02 17:58:50 (permalink)
Joeymir- Thats honestly what I was thinking tbh. According to userbenchmark the 4790k is only 14% better than the 4790s (when its not overclocked) so with 4790k currently going at $150 I didn't think the upgrade was worth it.
 
Its just after running user benchmark and other benchmarks i just cant pinpoint a source for such a drastic fps difference in games between my brother and I.

I am trying to game at 1920x1080 and I have a 144hz montior so as long as i'm above 144fps i'm good

Is your brother gaming at the same resolution?
 
I know you guys are saying that there is not much bottle neck with that CPU --> GPU but keep in mind that at 1080p the bottleneck is more then if the card was pushing 1440 or higher
 
How much of a split was there between the 1080 and 4k benches?

We're both gaming at 1080p since our monitors are 144hz 1920x1080

I didn't run a benchmark on his pc on 4k jsut compared 1080p gaming performance

Hey also another quick question, I installed an evga z87 classified so I have 4 ram slots. I have two sticks of ddr3 that run at 1867 MHz (dual channel) and an extra 4 gb stick.

Should I go for 3 total sticks and 20 gb ram? Or just use the two fastest sticks in dual channel?

Stick with Dual-Channel no questions asked. 16GB is or *should* still be ample enough RAM for the time being. And I didn't expect 144Hz - 1080P, in which case I would indeed keep an eye out for a 4790k. With a good cooler, you could likely expect at a minimum 4.4Ghz on all cores, but may even get over 4.7Ghz. This would indeed help 1080P - 144Hz performance. Then sell off your old CPU and be set
