so... my MOBO bottlenecks my CPU, which bottlenecks my GPU?

That's a strong possibility, i have and ASUS M5A99FX PRO R2.0 sitting here from my old FX 6300 build if your thinking about upgrading your Mobo

appreciate the offer but i live in Israel so i don't think we could pull it off. that kinda sucks though... i was planning of buying an intel based PC after this one dies out... guess i'm going to need to stick with AMD.
how much do you want for it? just out of curiosity.

About $90-100. I hope you can work out something for your PC. I know how bad you feel, (Been there).

ok so it turns out i did managed to OC it a little bit (20.5 multiplier) and i see a pretty big improvement. it's still flaky at times but it's mostly from 70-90. i did notice that performance degrades and that my CPU is on the high side (62 degrees). does it still mean that it's the MOBO that bottlenecks? how can i be sure? also what mobo can you recommend that is cheap? i'm probably going intel next time i'm upgrading so i don't to spend too much money.
and one last question, does installing a new motherboard means re-installing the OS and everything else? like does it formats your hard drive?

I think what you need is a better CPU cooler.

But yes next time you do a major system upgrade I suggest going to intel.

AMD is slipping further and further behind in CPU performance (not a fanboy)

Yes you have to re-install the OS which means format your HDD or you'll have driver issues but if you can live with the performance your getting, just save up for Intel Skylake next year and get a better cooler for now. (Cooler master hyper 212 evo) will be enough for even a 4.5ghz OC if your mobo can handle it.

Definitely stay clear from AMD. Going back a few years, AMD was a serious contender for bang for buck components...right now they just aren't cutting it at all and you're better off spending the extra couple hundred dollars for an intel setup. 2014 AMD is just....junk to put it plainly. They really need to pickup their game.

If I was in your situation, I would save my money and wait for skylake. However, skylake is not due till the second half of next year (and might get delayed). They are promising increased power efficiency with greatly increased performance among other things. AMD are hot cpu's. So between now and then, I'd source a second hand aftermarket cooler which is compatible with your cpu, give it some extra air and continue trying to overclock and hold on till next year. We're here to help an I'm sure we can get your cpu overclocked to a good level (with an upgraded cooler).

I'm yet to look up your mobo so I'll do so and report back here. Could be an issue with bottle necking. But in the mean time, definately start sourcing an aftermarket cooler for this super hot chip you have.

It's hard to say, but try to set multiplier to x22 (4.2ghz) and seeing that your stock Vcore is 1.425 set it to that also disable turbo core and play BF4 then tell me your results. Check temps also (core/package)

so i should touch anything besides setting the multiplier to x22 and disabling turbo core? nothing else at all?

When you overclock I would set the CPU voltage to manual to make sure the motherboard doesn't crank it way up.

When you set it to manual make sure it isn't set to anything higher than normal for the time being

But..um seriously you need a better cooler. The stock one barely manages at stock clocks

ok so i tried to OC and my PC didn't even boot up so i think i'm gonna get a new MOBO. also as it seems it's not even compatible with my CPU (AM3), so is there a chance i might have damaged it?

update: i jjust found out i have rev. 3.1, meaning it does support AM3+. It also says it on the box

ok i ran PCMark 7 on the free basic version and i got 3186 points (i think the test was PCMark suite). sorry for spamming i just want to know if i should but a new MOBO.

It's pretty simple actually. Your motherboard doesn't support AM3+ CPUs, only AM3. Some motherboards can run AM3+ even though not supporting it fully. If you are sure that your motherboard is the specific brand: GA-880Gm-D2H you should get it replaced. Some AM3 motherboards would support AM3+ CPUs with a BIOS update but I've looked at Gigabyte's support site and it doesn't seem like there is a BIOS update supporting AM3+. You will probably not get the full potential with that motherboard, sorry. But I guess you can try updating the BIOS to see if that should help, but I doubt it.

AM3+ socket is for FX CPUs so go get a motherboard that supports that.

AM3 only fully support Athlon II/Phenom II

Okay, well then it's not that simple... Have you tried updating your BIOS?

BTW if it supports the CPU, chances are really low that it should bottleneck your CPU. It can limit your overclock abilities but not bottleneck a stock clocked CPU unless it's defect somehow.

http://www.gigabyte.com/products/product-page.aspx?pid=...
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

it even says that it supports AM3+ on the box. what i'm trying to figure out is whether or not my MOBO is bottlenecking or how i can check that.

it also doesn't specifically list fx8350 in the cpu support list either...
http://www.gigabyte.com/support-downloads/cpu-support-p...
one bit of good news is that the mobo does support other 125W cpus however, so you are unlikely to blow up the vrms on the mobo... (some older mobos only went up to 95W so a 125W cpu had the possibility to damage the board, mainly the cheap ones though)

You'd need to monitor the clocks on the individual cores when gaming (under load). If the clocks stay up nicely it should be ok. I believe amd had their own little software for that, the amd overdrive?

thanks, i'll measure the clocks while gaming.
but it seems i was wrong again: i checked the box again and it says its "rev 4.0". having said that, according to the support list on gigabyte's website (http://www.gigabyte.com/support-downloads/cpu-support-p...) the 8350 is still not supported.

can you recommend a cheap MOBO for the FX-8350?

Any 970 Chipset should be fine.

Post the model of the motherboards you're considering and we can check. BIOS update may still be needed before supporting fx-8350.

Those are good option, but get the 990 chipset if you can cause it will have better VRM for overclocking and also they both should support the FX 8350 out the box.

You definitely should try "core unparking" as You got a FX 8350!
A lot of AMD BF4 players could get rid of the FPS drops by doing that.

If that does not help, reinstall BF4 and reinstall video driver AFTER that.

Too avoid redownloading BF4 do this:

    Goto BF4 installation directory
    Backup Data, Update, Update2, Update3 directories
    Deinstall
    Copy Data, Update, Update2, Update3 back to the BF4 installation directory
    Reinstall BF4

By doing this Origin starts installation, gets the core files and some other stuff, finds the data files and proceeds straight to the installation. It takes just a few minutes.

Stay away from overclocking as it is useless concerning FPS drops. And don't mess up the BIOS!

Its a 100 % bottle neck thanks to your Amd cpu, now i have also been using the same pc specs as u said, i simply sold my fx 8350 and moved on to INTEL chipset mobo and cpu, at first i was using my r9 290 on z77 extreme 4 with i3 at 3.3 ghz, i honestly saw a ton of performance improvement, next thing u know i realised that amd processors were just good at overclocking and nothing else, after using this setup for 3 weeks i moved on and installed an i7 3770k overclocked to 4.4 first on stock cooler, then 4.8 ghz on custom water loop, long story short cutting all the bullshit out !!! Remove your mobo and cpu buy some intel shit and voila happy gaming, and if this do3s not work u can punch me in my face for wasting your money !!!
