im in the market for upgrading my cpu and am giving serious thoughts on intel 4790k is it worth the upgrade? i heard that when games come out that are using dx12 that my 8350 will run better than games in dx11? game i currently play with my 8350 are: gta v, arma 3, arma 2, dayz sa, bf4, bfh. with gta v i get frame drops and with a 4790k and my r9 290 i would think that i wouldnt get much frame drops and my frame rate would stay 50-60. i also stream. im thinking that the 4790k will give me a more consistant frame rate.
 
Solution
arma 2 and 3 work poorly with amd graphics cards as far as i know. bf4 works well with both amd gpu's and amd cpu's, so i dont know why frame rates would be dropping with that game. What i would suggest first, is identifying the bottleneck.

So, pick a game that you have an issue with, load it up with all your desired detail settings at 1080p. Now drop only the screen resolution to about half of what you had, like 720p or similar. If the fps dips you had previously are significantly reduced, then you need more gpu power. If not much changes, and you still get the fps dips then its your cpu. I would be looking at the newer skylake cpu's rather than haswell though, they are beefy as for gaming.

Solution
If you're not happy with current performance from the fx 8350 and you've tried overclocking it and anything else to improve performance then intel is your next logical option. Anything amd that you switch to is going to be a side grade from what you have so there isn't another level higher to go in amd's lineup. Intel cpu's typically do give more consistent frame rates and higher min frame rates which contributes to the smoothness of game play. The lower the fps dips down the more choppy it can make it feel even if it's only brief or once in awhile.

Dx12 will help all cpu's but will likely be more beneficial to some of amd's cpus since they're already struggling to keep up. Less work for the cpu the better. The trouble is unless those games come out with a massive update or find a way to alter their game engine to take advantage of dx12 they will remain dx11 games. A game has to be coded for dx12 to take advantage of it. Assuming they don't patch older/existing games, none of the games you mentioned will benefit from dx12.

Another thing potentially working against you is using an amd gpu with amd cpu. Many times amd gpu drivers are more intensive/complex and require a stronger cpu to process. Ironically enough nvidia drivers usually place a lighter load on the cpu which is more beneficial to amd cpu's with lower ipc performance.
 


I did the test you suggested on gta v and i lowered res from 1080p ti 1280x768 and not much changed the fps was the same so this helped me alot on knowing if i needed an upgrade i have an r9 290 so i didnt think it was my gpu anyway thanks i have a little bottleneck with my 8350 and my 290
 

yes, so it is indeed a cpu bottleneck. I would strongly suggest going for skylake i5 cpu over the older haswell architecture though if you can, best to stay with the latest, and it is a good amount faster. Or even consider socket 2011 cpu's....
 


i would get a 6600k but i dont want to spend the extra on ddr4
 
the price diff between ddr3 and ddr4 for the same speed (eg 2133) ram is nothing. Ram speed can also be a bottleneck. You could sell your old cpu, motherboard and ram and put that all back into the new stuff your buying. And, there is also some boards that support ddr3 and ddr4 ram if thats a concern.
 


i dont think its my ram my ram is GSkill ARES 1600mhz 9-9-9-24 4x2gb, 8gb ram. my understanding is that the 6700k supports both ddr3 and ddr4 and the 6600k only supports ddr4
 

http://ark.intel.com/products/88191/Intel-Core-i5-6600K-Processor-6M-Cache-up-to-3_90-GHz according to specs both are supported, with the correct motherboard.
"Memory Types DDR4-1866/2133, DDR3L-1333/1600 @ 1.35V"
 
As iam2thecrowe pointed out, some boards are ddr4, others may be ddr3 or ddr3L. Ddr3L is low power (1.35v) ddr3, not standard 1.5/1.65v ddr3 used in ddr3 systems right now and intel doesn't officially support it. Running the higher voltage standard ddr3 even if a motherboard supports it 'could' (not certain to what extent other than intel warns against it) - damage the cpu since the memory controller is on the cpu.

Considering ddr4 is just now coming to mainstream and ddr3 has been in play for years I highly doubt ram is the bottleneck or all mainstream (non x99) systems the past several years would be performing poorly. That's not the case.

Skylake is too new yet to determine what ill effects may result from running ddr3 at the higher voltages but if intel warns against it there must be a reason. I can't see risking a $350 cpu to save less than $50 on 2x4gb of ddr4 2133. If the budget is that tight, may as well get the 4790k and save money not only on the cpu but the motherboard and ram (by reusing what you have). The performance difference between devil's canyon and skylake is minimal.
 


from some reviews the gains are quite good (more than 5%), it depends on the gpu they used to test. If not overclocking i certainly agree with the xeon option, and yes its extra threads may be beneficial for streaming.
 
How do i put this in the quickest of manners, Its worth the switch (dont even think twice)

P.S. The minute i saw you played arma, i immediately scrolled down to comment this.

Side note: I use to own the 8350 before i switched over to what i have in my signature below (i7-5820k at 4.5ghz)
The framerate difference in arma between the 8350 and intel is unreal (intel wins without even breaking a sweat by 30 to 50 frames difference)

Since you mention streaming ill try to help there as much as possible as well, i streamed a bit on my new rig as well for just a bit of testing on it (My motherboard has a built in hardware streaming engine though so it helps ALOT) and while streaming i lose ZERO performance of framerate at all.

When I am streaming i forget its running all the time because it has literally no framerate difference between streaming and not streaming
 


Unless you have ants in your pants, I would suggest waiting 11 months for the release ofn AMD Zen desktop cpu's. They will match or surpass many I7 cpus and will offer more cores for the better coded multithreaded applications. The floating point performance of Zen will be at least double that of the current FX8350 cpu as well.. I guess that your poorly performing games are those that have no support for more than 2 cores. Thes dinsoaur programs are designed by brain-dead companies that are in bed and embedded with Intel.. Just wait a little longer and you will have an AMD solution for your problem.
 


Amd would be lucky to surpass ivy bridge. AMDs only hope is to offer good performance for a good price, amds current line up is bad performance for a good price.
 
Anything's possible but even with the release of zen next year I think odds are against amd matching intel's ipc performance. I'm sure they'll improve from fx but only time will tell and based on past 'intel killer' predictions from amd vs their actual results I wouldn't hold my breath. Amd already offered more cores and their predictions and hype around bulldozer resulted in a huge setback for them. Zen will have to pull of some serious silicon wizardry to even try and remain competitive at this point.
 


I really don't think it's your cpu. I have that exact same setup. An 8350 with a 290x and that game runs smooth as silk. I have no frame drops whatsoever in any games that I play at 1080 on max settings.
