BF4 runs at the EXACT same fps on Ultra (No AA) as Low settings. And if I turn on 4x AA its almost unplayable because of fps drops from 70 to 20 at random and frequent times. It also has random drops on League of Legends (which only runs off a single card). Ive tried all the below:
-Reinstalled Drivers
-Did virus/malware scans
-Reinstalled the games
-Took off my overclock on processor and gpu.
-Temps never go above 50c on CPU and 60c on GPUS
-No voltage irregularites from the PSU
-Checked stabilty of my 4.2ghz overclock for 5 hours on prime95 with no errors
I am ready to switch to a 4670k with an asus maximus hero if itll fix it.
Thoughts?

How much Ram are you running? And i doubt your 8320 is bottlenecking. Im on a 6300 with a 760 and getting 80fps on ultra8gb Corsair XMS3 1333mhz
I personally dont think your GPU can handle ultra with 4x aa. My 760 at 4x aa will be like 30-40 fps. at 2x aa its at 60fps. With aa off its at 80fps.
Whats it like without AA on?

Yeah but this is crossfire 270x's. and with no AA i get 60-130fps depending on the area with about a 75fps average. But thats exactly what it gets on low settings as well. And both settings come with drops to 20-30 fps randomly and frequently

amd inc cf doesn't go well with these game not to mention bf4 is really bad optimized and you are not alone in these situation so i really doubt you are being bottneck more than drivers or the game it self , it seems software fall behind the hardware Like I said, it also suffers frame drops in league of legends, which runs on single card, not crossfire. Its weird

I am running an AMD FX8320 @ 4Ghz and crossfire AMD 270x's and i get very good performance in Battlefield 4 with ultra settings and 2xMSAA. I easily get 80+ fps .The Mantle update is out soon.
Do you know what Mantle is?
Why not wait and see if it fixes your problems?
Mine runs it as good as yours, other than random drops to 20-30 fps. And it does the same thing on single GPU when i play LoL. And I am aware of mantle, which is why I want to keep my 270x's

yeah the cpu runs 70%-100% while the GPU averages out at about 60-70%And yes frame pacing is enabled
That answered about 1/3 of my questions
Something like GPUz will allow you to compare the use of each GPU ('average utilization' does not do us any good) -- one of your video cards is likely to have much higher utilization than the other video card ... especially when your frame-rates drop. One solution to this issue is to disable frame-pacing.
Be sure you are not running in a borderless window. Verify that you are actually playing in full-screen mode.
This is an issue with both Intel and AMD CPUs (see Jay's post) and if you have actually done a web search for solutions you will see how wide-spread these issues are with both CrossFire and SLI. There has even been a patch released in the last few weeks regarding multi-GPU setups. Have you tried the new multi-GPU patch?
You have a configuration issue, so your thread title reads more like flame-bait, and, by not telling us ALL the exact steps you have taken to try and address YOUR problems, we're out here shooting blind, and for the most part, wasting our time trying to help you.

I'm sorry for the lack of information, I will use CPUz to get you the results, I appreciate your help. And I will try it without the frame pacing. And as for the drivers, i have the latest ones that AMD has posted, is there a new driver that came out in the past day that I am not aware of? Also crossfire issues aside, I still havent really heard a theory as to why single card performance in a game like League of Legend would be bumpy and inconsistent.

I'll save him some trouble - BF4 is an unoptimized POS and driver makers are left picking up the slack, which, to this point they are still running behind. I've tried everything, scanning the web for hours, to find nothing addresses this issue. The only controlled variable at this point is the game. Benchmark scores for me are comparable to a single 290x.
I'm running your bigger brother - FX 8350 - at 4.4ghz with 270x's in Crossfire (1100/1425 - rock solid stable). GPU utilization (both GPUs) in 32 player BF4 goes from 85% at best down to 30% at worst making it more or less the same performance as a single 270x. Funny thing is that in wide open maps I get my GPU's up to 85% only to have them randomly drop to 30% when I'm staring at a building with no one around. Blows my mind.
CPU usage is 50-60% with a single core rarely reaching 85% and definitely not staying there for any extended period. Driver updates have incrementally but still unacceptably improved performance since 13.10.
Rest of system:
850w Corsair PSU
12GB 1600mhz ram
OCZ Vertex SSD
1080p resolution.

Why not wait and see if it fixes your problems?
Do you get 80+ fps in 32 and 64 player games where the CPU overhead pounds your frame rate into the ground? Mantle will help. It will get all the overhead junk out of the way and let your GPUs sing (hopefully).

UPDATE:Upgraded to a 4770k with a z87 mobo and it ran flawless at 80-120fps, no dips or anything. I did end up selling both cards to get a GTX 780 though. But it does look like the 8320 was in fact bottlenecking my crossfire 270x's
You did run the 4770k with the Crossfired 270x's using the same drivers, correct? We need to eliminate the driver issue first, but I wouldn't be surprised with regards to the 8320 bottle necking.
