Which CPU should I buy?

[OttoFIN]

Shortly: I want to buy a new CPU that could run Arma 3 multiplayer smoothly. (yes I know that is asking alot). My budget is about 450€.

These are my specs:

Processor: Intel(R) Core(TM) i3 CPU 530 @ 2.93GHz
Graphics card: GeForce GTX 750 Ti
CPU: Intel(R) Core(TM) i3 CPU 530 @ 2.93GHz
CPU Speed: 2.9 GHz
RAM: 8.1 GB
Free disk space: 241.2 GB
Sound card: NVIDIA Virtual Audio Device (Wave Extensible) (WDM)

Well if you have 450 you can buy a great cpu

[Giannara]

Bare in mind that you have to get a compatible mobo with your cpu.

Is that sarcasm or.. ? 

[Nick Lazanis]

Not sarcastic at all. With that money you can upgrade your PC really well

[OttoFIN]

Ah, well now I just need to know what CPU I should buy to run Arma 3 multiplayer smoothly and maybe some other games too.

Try using pcpartpicker, its very helpful in creating a PC

CPU that could run Arma 3 multiplayer smoothly.

Your performance in Arma multiplayer is heavily, heavily reliant on the server's processor. That's why you can change your video settings in a bad server from your usual graphics settings to lowest with zero effect on performance. It's also why you get considerably more frames in singleplayer compared to multiplayer. If this is the sole reason you want to upgrade your computer and you're only upgrading your CPU, you might want to hold off. There's not much you can do.

Also, king of the hill servers and stuff lag the worst. If you're getting 10 frames in those servers, so is everyone else. The idiots that run those servers put the client limit to like 150 and give everyone the ability to nuke the map (granted you have the cash). If you've ever played in a realism unit, you'd know what a good arma server run by sensible people is: 100 player servers where you can get 30 frames max. It doesn't get any better than that.

How can there be people that can run the multiplayer with 60 FPS?

I play DayZ mostly now, so I know which CPUs are best for Bohemia Games.
There are 3, which I personally have one of them:
1. i7-4770 3.4 GHz (this is mine) - the lowest tier one, even though it is a beast of a CPU.
2. i7-4770k 3.5 GHz (OC'd) - can be overclocked up to 4. something GHz.
3. i7-5930k 3.7 GHZ (OC'd) - the most beast CPU intel has released yet. Built for running any game smooth and sexy.
The prices are all dependent on the CPU of course, if you choose the highest tier one, it will most likely cost a lot of money.

Several reasons: Low player count, low amount of spawned entities, low amount of explosions, low amount of vehicles, low everything. small 20 player PvP servers have the ability to give people 60 fps in multiplayer. Big, shitty king of the hill servers and stuff with a bunch of idiots running around and blowing things up will always lag

Also, this. If you're set on balls-to-the-wall upgrading your CPU. Just don't be disappointed when you get an extra 2 frames on king of the hill.

And dayz servers lack very many spawned or cpu heavy entities, so they run well.

meh i have a I7-4790k at stock speeds that runs perfectly fine with ARMA. Just make sure your motherboard has the right socket. I would definately reccomend that though.

I stream though, so I get like 20 FPS.

The best CPUs are tops $300, they're also the fastest part of your PC so you shouldn't drop too much on them if the rest of your rig isn't in the same league. I'm not sure how you have your RAM if it's 2x4gb or 1x8gb, but if possible you should upgrade that to 16 gb. RAM is cheap. OS uses almost 2gb on it's own, and if you're leaving your computer on for weeks (standby mode or not) you will end up having memory leaks over a couple gigabytes. The extra RAM will be good so at the most important times you're not going to have massive hangs waiting on your page file. Trust me, I'm on 8 physical and my usage sometimes goes up to 10. I'm not sure if ARMA is multithreaded but not many things are, i7 is more or less a luxury unless you're rendering 3D animations so it's best to get the i5 version of the same chip.
