Which CPU to buy?

[Jim4]

Hello guys!
I have 2x Fury X's and i need to upgrade my CPU to avoid bottleneck! At the moment i use one Fury X because my CPU right now is the i5 4690k and am sure i am going to have bottleneck if i use my second Fury X too! I am thinking of buying one of these CPU's:
i5 8600k
i7 7700k
i7 6800k
I was thinking of buying the i7 8700k but its too expensive in EU!
I would really appreciate if you help me! Are these CPU's strong enough for my cards? If not please suggest me others!

A better question is.... What OS do you have? Intel's Kaby Lake and newer CPUs no longer "support" Windows 7 / 8.1

 

[zyh1987]

my 2cents here:
i would say 7700k is slightly faster than 8600k.
both needs to be oc a bit to get the most out of the CPU, having said that, but the difference should be quite small. having the 2 extra thread should help manage things in the background a bit better than 6 core i5.

Windows 10

I would go with the 8600k. The 8600k will get better fps than the 6800k and the platform is cheaper. I would also take the 6 actual cores of the 8600k over 4 cores and hyper threaded on the 7700k.

So you recommend the 8600k ?

So the 8600k will not bottleneck my GPU's right?

I5-4690K is still an excellent processor for gaming.

What is the make/model of the rest of your parts?
What is the primary use for this pc?
Gaming or batch applications?

For gaming today I would sell both furyX cards and replace with a single GTX1080ti.
Many games no longer support dual gpu.
dual gpu is prone to stuttering and screen tearing; avoid it if you can.

Or, wait. Later this year new high end cards are expected to launch.

If you play fast action games, your 4590K is probably fine and you should concentrate on better graphics.

OTOH, if you play sims, mmo, and strategy games, single thread speed is all important.
For that, either 8600K or 8700K is as good as it gets, with 5.0 overclocks likely.

Between the two, favor the I7-8700K if you play multiplayer where many threads are good.
For most other games, 2-3 threads is all they can effectively use.

I am using my PC for gaming and nothing else! I recently bought my 2nd Fury X ( i already had one ) for a very good price(350 eu)! I dont think the 4690k will be enough so i am upgrading! The games I play at the moment are GTA V , LoL , Fornite , ACreed and The Withcher 3 !Do you think that the 8600k will be enough for this GPU power or not?

No, the 8600k is one of the best CPUs in the world for gaming. If the 8600k will bottleneck your GPUs, then any CPU will bottleneck them.

I whole heartedly agree with geofelt, sell those 2 Fury Xs and go get a 1080ti. You will get much better performance and your electric bill will thank you as well. After selling the 2 Furies, you should not be that far away from having the money to buy a 1080ti.

 

[madmatt30]

With froggy & geofelt too.

Runjing a 500w+ furyx crossfire setup with a limited 4gb vram makes no sense now when a 1080ti will crush them performance wise 90% of the time.

Infact a 1080 non ti would be comparable too .

Definitely the 8600k as already suggested too.

 

[faalin]

2 fury x on a stock 4690k is about a 23% bottleneck
2 fury x on a stock 8600k is about a 12% bottleneck

I would keep the 4690k and ditch the 2 fury x cards for a better single card.

 

[feelinfroggy777]

I would not take too much stock in a bottleneck calculator. They don't really tell the whole story as there are a lot more factors than just the GPU and CPU being used. Most importantly for gaming is resolution. For gaming at 4k, the bottleneck almost certainly moves towards the GPU and it is all off of the CPU. Where at 1080p the CPU will be a much bigger bottleneck. Then CPU heavy or light games will have also change how the system functions. For example, on BF1 he will get much better fps on a 8600k vs the 4690k because it really likes the extra threads on the 8600k.

 

[zyh1987]

I recommends 7700k based on cpu comparison, and I do recall your budget are limited from your previous posts . Unless you are planning to upgrade to 8700k soon, 7700k will be my recommendation.

 

[Jim4]

Guys a friend of mine just told me that the Ryzen 2700x and 2600x have released! I will probably go for the Ryzen 5 2600x which is 4.2Ghz 6 cores and 12 threads! What do you say guys?

 

[feelinfroggy777]

I would wait for the reviews. Ryzen CPUs are excellent, but Intel has a lead in gaming. Maybe the Zen+ will narrow the gap.

Do you currently have a bottleneck right now, & if so what are the symptoms? Based on original testing (https://www.techspot.com/review/1024-and-radeon-r9-fury-x/), this GPU is geared towards 1440p gaming, with the potential (depending on the game) for playable performance at 4K...which means that 1080p gaming should be a snap. At 1080p, yes, a CPU might hold a Fury X back (let alone 2 in CrossFireX), but again that will depend on a) the particular game & b) what your monitor can even push out (& in many cases enabling Virtual Super Resolution will help offset that).

As previously mentioned, whether or not 2 Fury Xs in CrossFireX will have noticeable performance improvement will depend on the game involved (https://www.techspot.com/review/1033-gtx-980-ti-sli-r9-fury-x-crossfire/), but the newer the game is the more likely that the difference will be miniscule.

With that being said, if you're actually having some performance problems, there are a couple of things you can do:

■ As pointed out, sell both Fury X GPUs & buy a new one. With the current price hikes on the high-end GPUs, chances are you might break even if you settle for a GTX 1080 (not the TI version, as that can run close to $1,000 USD), or even a 1070TI. However, the main benefit from that is avoiding any CrossFireX issues & a reduction in power/heat.
■ Keep the Fury X GPUs, & consider replacing your i5-4690K with a Haswell Core i7. You have a Haswell Refresh Core i5, so your motherboard should be able to handle the i7-4790/4790K (& you should be able to reuse your existing cooler). Aside from a slight uptick in clock speeds, your biggest gain is going from a 4C/4T CPU to a 4C/8T CPU, & in some games that may give you a performance boost. Plus, it's nearly guaranteed to be able to "handle" just about about GPU in SLI/CrossFireX.

Guys would you give 280 bucks for a new r7 1800x ?

Not for a gaming rig. An 8600k is cheaper and will get better fps than a 1800x. If you are building a workstation then the 1800x is a nice choice. But games wont be able to use all of those threads. They will just sit there idle doing nothing.

Yeah you are right ! The 8600k is a freaking beast! I saw some benchmarks and it outperformed the 8700k too in some games! How's that possible?

 

[feelinfroggy777]

Because many games don't scale with more cores. This is why the 7700k, 8600k, and 8700k are basically within the margin of error in many games. They all have the same IPC, just more threads. Those extra threads don't do much for today's games.

Go for the 8700k maybe, but i would say the new ryzen 2000 series is the THING! Intel have made so many strange choices, and they change their sockets all the time making you need to buy the most expensive and newest ones! 2600 or 2600x are coming out very soon 😀 Good cpus for everything, not just multitasking!

R7 1800X would be more of a side grade in all areas except tasks that could take advantage of lots of threads which isn't gaming so much right now. If you're streaming or doing content creation it would be a good idea.

The bottleneck really would depend on what you're playing. I think a bigger concern would be using Crossfire to begin with. It has variable scaling and support. The idea of selling those cards and getting a single GTX 1080 or GTX 1080 Ti would be a lot better. I really don't recommend SLI or Crossfire to anyone except for extreme 4K ultra builds.

Personally I'd sell the Fury cards and get a GTX 1080 or GTX 1080 Ti and if the performance wasn't what I want then I'd go forth with an i5 8600k build. Currently the ideal gaming CPU at the moment. 8700k isn't worth it unless you need the hyperthreading and most don't.

The new 2700X is fairly competitive with the 8700k based on initial benchmarks which we will see more of starting April 19th.

I'm between 8600k and 2600x! I will wait until April 19 to see the benchmarks! I will ask you again in a few days to help me choose! I dont know that much about computers than you do! Thanks a lot guys !
