Im inbetween the buying of a 2500k and fx8120.
Theyre both unlocked and good processors, but which one performs better doing these things:

Playing battlefield 3 WHILE recording with fraps.
Playing battlefield 3 WHILE livestreaming it to twitch.tv

Im sure i will get a great performance while doing not these tasks with any of these processors, but which one performs better while recording and livestreaming ?
 
i5-2500k, but recording would depend on hard drive speed and where you are recording from. First install the game onto an ssd and record to an hdd. As for livestreaming that would depend on your internet connection!!

Well, wouldnt the 8 cores be a benefit over the 4 core 2500k ?
And yes, i have a seperate HDD for recording and my internet speed is really good.
And my OS + game will be on SSD

8120 better in mega tasking..
that's mean if you running 4 or 8 program simultaneously..

if you running just 2 program..(multitasking), processing power of 2500k still better than 8120.

also in gaming, if you play in hd (1920) resolution, there's almost no difference, no matter what processor that you use.

The FX-8120 is "sort of" an 8-core processor. It has four Bulldozer modules, each of which can handle two threads. The improvement in performance from running a second thread in the module is better than that of running two threads per core using Intel's Hyperthreading but not as good as (but less expensive than) having 8 actual cores. Where between the two it sits varies heavily depending on your task. The FX-8120 acts much more like a real 8-core CPU in tasks like rendering and video encoding, but more like a quad-core in other tasks.

The i5-2500K would likely be the better CPU as most games don't use more than 2-3 threads, and the per-thread performance of the i5-2500K is higher in Windows games than the FX-8120. The extra threads of the FX-8120 may help with making the system feel smoother if you are doing much processing of the video, such as doing an on-the-fly encoding when recording or if you are running a lot of stuff in the background. The game will run slower than the i5-2500K (usually by an amount that does not matter, such as getting 80 fps when the i5-2500K can get 100 fps) but will be less stuttery. Alternatively, you can get a Sandy Bridge that has HyperThreading enabled, like the i7-2600K or i7-2700K and also be able to handle 8 threads. That should give you at least as good of performance in any situation as the FX-8120 but at a considerably higher price.

If the video recording is simply a dump-to-disk, its performance will depend on how fast your hard drive is and how busy it is. The recommendation to run the game off an SSD and dump video to an HDD is a good one.

So fx8120 would handle better me having skype, msn, teamspeak, xsplit(livestreaming program), itunes, steam and BATTLEFIELD 3 open at the same time ?

not just open..but working and using processor power.

such as, video rendering with vegas, 3d animation rendering with max, converting video with cyko, watching 2 blueray video, while gaming..


who will do that task anyway..:D

So basically - if i have the money: Get a 2600k/2700k.
If i dont have it: get a fx8120
If i want ONLY gaming and have no money: get a 2500k.

is that correct ?

i prefer like this..

if i have much money: Get a 2600k/2700k.

If i dont have that much money: get a 2500k.

If i want ONLY gaming and have no money: get a 2500k.

if i don't have money, but still want to do some gaming and multitasking stuff: get 960T, unlock it, overclocking it till last juice and hope that next amd processor (piledriver or whatever) will be better and not making big dissappointment..(just like i do..:D )

But if i dont have that much money and want to livestream/record games WHILE getting good performance from battlefield3, guild wars 2, diablo 3 etc.

Also, 2500k + equivalent mobo of the one that i would get with fx8120 is the same amount of money that i would get fx8120 + mobo + SSD + razer abyssus mouse(my mouse is broken)

I could get 2600k + mobo thoo... but then i would just have to stick with my 5400rpm sata2 hdd and get no ssd which is ***.
 


So it sounds like the FX-8120 would be the better fit for you, since it would allow you to purchase the SSD and mouse for the same price as the i5-2500K + motherboard. The FX-8120 will perform well in modern games- hitting that 30 fps minimum required for good gameplay will be much, MUCH more dependent on your GPU than your CPU with the CPUs we are talking about here.

well ive got a 560 OC on 925mhz by factory and im getting a mobo thats SLI compatible so i can collect some more money and get SLI :p

Anyways, so you would suggest an fx8120 + ssd + mobo rather than a 2500k + mobo for livestreaming and recording games.

2500k + equivalent mobo = fx8120 + mobo + SSD + razer abyssus mouse

can i know what brand/chipset/type mobo that you want to buy..?
get a best board that you can afford while you choose 8120 as your processor.
because, 8120 is s*ck when running in standart clock (3.1Ghz), but great while overclocking.

in standart condition, performance is par with 960T unlock..(somehow 960T unlock is little bit better.)
that's why i suggest about 960T. cheaper than 8120, but you still got about performance point.

And it will serve you well for livestreaming and recording games.

4 core for game, and 1 core for live streaming and 1 recording games....

 
Anyways, so you would suggest an fx8120 + ssd + mobo rather than a 2500k + mobo for livestreaming and recording games.

I wouldn't get that combo (8120/SSD/Mobo) JUST for that task, but if you can't get a SSD AND the 2500K + mobo and mouse, then yeah, that's probably the better option for a total overall balanced build for you.

i dont get it tho, i will have skype, steam, teamspeak, battlefield 3 and itunes or winamp running at the same time. That means playing battlefield3, while answering questions on chrome, listening to music and streaming with xsplit.

How is 4 cores better than 8

what motherboards are you looking at? If you're worried about 1 PCIe socket only running at X8 instead of X16 it doesn't matter as the difference is so tiny it doesn't matter

Well...
http://www.galador.ee - this is the place im gonna buy from (translate with chrome).
I want the best bang for the buck - max cost 450 euro.
Best solution:
Cheap as possible
+ SSD
+ MOBO
+ CPU
+ Can handle livestreaming + answering to questions on chrome + itunes + battlefield 3 + skype + teamspeak AT THE SAME TIME.
+ Razer mouse (30-50 euro)

different technology cause different output of processor power..

for example like this. 4 tigers againts 8 wolves....:D
that's what happened with intel and amd..

actually fx 8120 is not really 8 core, but just 4 module, which is each module consist 2 processing unit.
like hyperthreading in intel, but amd choose to use physical unit rather than virtual like intel.

so you can said fx 8120 "just" another quadcore variation from amd.....

well, 2500k doenset have hyperthreading and is 4 cores..how is it better than 8120 tho... i will be rendering videos with vegas aswell after recording my gameplay of bf3, gw2 etc.

i guess maybe he think will boring when waiting vegas movie rendering , and not have time to wait, he play game again and also recording and livestreaming it.. ;)

4 tasks in the same time..rendering vegas movie, playing game and recording it also livestreaming ..... :D

wow..watch your electricity bill... :pt1cable:


*actually i think..maybe you'll need dual xeon class processor for all those tasks....:D
