You only have a 460 so no wonder you don't understand my situation. lol.
What has my 460 got to do with it?
I run Bf4 on high @ 1080P with 45 FPS.

You have basically summed up why you get low FPS with mantle.
You do know the I5 2500k and the I7 3770K both have 4 cores?
Please watch and understand this

Intel 8 core consumer CPU's will be hitting the market in the 2nd half of this year, with a new chipset and will use DDR4 memory.
This video will explain how to use D3DOverrider https://www.youtube.com/watch?v=WhhXqgOsFbM
Basically it gives you a stable frame rate by enforcing triple buffering.
Mantle works fine for me.
It works well for some but not others, I dont see how OP thinks a I5 2500k will bottleneck a R9280x
The whole point behind mantle is to take load OFF the CPU should you have a ****ty low end CPU.
And the 2500K isnt ****ty.
First, just so we're on the same page, the i7-3770k has 4 cores and 8 threads because it has Hyperthreading, the i5-2500k you have has 4 cores and 4 threads, it has no Hyperthreading. Hyperthreading gives around 30% more speed than a CPU without it.
Now Hyperthreading fools the system into thinking the CPU has 8 cores when it only has 4. The general consensus is that Hyperthreading does not improve performance in games, only programs such as Autocad and programs that require loads of threads.
From the benchmarks I have seen Hyperthreading in Battlefield 4 actually decreases performance than not having it on in the first place, this could be due to the game being poorly optimized (not surprisingly).
Personally I think you have wasted your money on getting the i7-3770k for gaming, if you are going to use programs like Autocad ect then it was a good investment. I would of gone for a 8 core AMD CPU instead. If you gain performance then good for you, please post the results as I would be interested in seeing how it compares to your i5-2500K.

Ive left out 1 very important question, how many FPS were you getting before you installed the mantle driver?
So you get 20FPS with dual R9 280x's with out mantel? Sounds like a crossfire bug.
Also whats your CPU temp when in bf4?
not 20fps without mantle but with mantle i get 10FPS. Without mantle it will dip to like 80FPS and make me stutter. hint cause of 120Hz monitor and no i'm not playing without sync. My games tear to much
What drivers are you using?
Uhm I said 14.3. i tried all drivers since since 13.12 and same issue
BattleField 4: V-sync issues observed on CrossFire configurations (with Mantle enabled) have been resolved
Here's from playing about 10 minutes with everything set to ultra and 4x MSAA 1920x1080, Mantle:
View attachment 106794
CPU average usage was around 40% maxing out at 59%, so once again if your CPU is hitting 100% something else is buggered
Have you tried running Mantle again after installing the 14.3 drivers, I see there was a specific issue with V-Sync and Crossfire in BF4 that was resolved
Quick breakdown of my machine:
Core i7-4771 CPU
Corsair H100i Cooler
Asus Z87-A MB
32GB Kingston Hyper-X 1600MHz (I run VMs that's the only reason I have more than 16GB)
Sapphire Tri-X R9 290 OC Edition
Intel 240GB SSD
Asus Xonar D2X Sound Card
Vantec Voltra 1050+ PSU
Planning on getting a second R9 290 in a couple of months time
Just thought about it now, do you use on-board sound or a dedicated sound card?
yet again you have 1x 290 and no crossfire and you run 1920x1440 and not 120Hz. you have i7 haswell and even you see almost 50-60% cpu usage so image my cpu.Mantle is only optimized for 290 and 260 gpu's. uhm yes I tried mantle again and same issue and even with a clean install of windows 8.1. They said resolved for r9-290 and r7-260 users but not my cards cause it's not fully supported yet....lol
Don't argue he's convinced it's a cpu bottleneck(it's not) and has already bought the new CPU...
OP where did you get it and how much btw cos I'm looking for one too?
PS: when this doesn't fix ur problem can I have it?![]()
I was thinking CPU thermal throttling, but that doesnt seems to be the case.
What about a unstable OC?
