I recently installed a second Asus GTX 760 and running it in sli mode hoping to get a performance increase in Bf4 but their is not even the slightest performance increase that you would expect from two 760s. I've tried everything to fix this!!!! I made sure that Sli is enabled, i've unparked my cpu cores, I've oc'ed my cards and processor, clean installs of both bf4 and latest nvidia drivers, no thing is working!!! i have done almost everything!!!! i have even messed around with the user.cfg folder.
my system spec are as stated bellow
AMD AM3+ FX-6350
WD 1TB Dest. Mains HDD
2x Asus Geforce GTX760 2gb ddr5 (sli mode)
Corsair RM750W PSU
Windows 7 Home OEM 64Bit SP1
DDR3 16 gb Corsair Vengance (2x8gb)
Gigabyte GA-990FXA-UD3
My frame rate stays about 55-60 avg. <-- also the average frame rate when just using 1 card
min. 33fps
max. 113fps
I have lowered the graphical settings and fps doesn't change!!!!!!! from low to Ultra!
Is it my system??? is it drivers?? Could it be that bf4 just hates me and wishes to see my cry???
Help is very much appreciated and thank you in advance :) 

PS---If it will be any use i can provide a list of things i tried to do to fix this problem
-Switching the cards around (using pcie x16 lanes)
-Messing with Nvivda profile settings for bf4
-Changing power management settings for my processor
-overclocking my processor
-overclocking my graphics cards
-unparking my cores
-using the user.cfg file to use all cores
-fresh and clean installs of current nvidia drivers
-clean install of b4
- Cursing at bf4 and the computer

I think I figured it out.

What monitor are you using at what is your refresh rate? :)

You probably have a CPU bottleneck because BF4 is very CPU intensive

Im using a tv as a monitor, 60hz refresh rate, 1920x1080p , and using an hdmi cable, vizio E321VL

There you go. You will only be able to get 60fps

Did you say you got 133FPS with the one card. Was that your result you got?

That was what I suspected at the start. You will get more than 60FPS on that however it is noticeable. As it is a 60Hz monitor unless it is a higher refresh rate.

I believe it's your monitor, you will need to have 144Hz recommend for SLI, especially 750 and above.

would getting another monitor be my only choice??

Yes getting a 144Hz would better as you are running SLI.

Nonsense, you only need a 144hz monitor if you are a hardcore pro gamer, not because you've got sli. 60hz and 60fps is perfect for most gamers. Sli 760 will just allow you to maintain 60fps across more aaa games at higher graphics settings.

see the thing is im wondering why sli isnt giving me the frames i should get

You will probably find that your cpu is what is limiting your system.
http://www.tomshardware.com/answers/id-1742828/cpu-bott...

If you do not have v-sync enabled then the refresh rate of your monitor (or tv) will not affect the frame rate (I could be wrong about it but given that your maximum frames per second is not 60 then I would bet on the monitor/tv refresh rate affecting anything).

Now is their something I can do to reduce or get rid of the bottleneck???

You could try using the console command (hit `/~ key to bring down the console) "PerfOverlay.DrawGraph 1" which will show you your cpu load, gpu load, and your frame rate. Watch the frame rate, if it drops down then look to see if the either the cpu or gpu are at maxed load with the other having a decreasing load. The one with the maxed load is possibly the one bottlenecking your system. I am not sure if the graph will tell you the max cpu load over all cores or if it will show the load on each core.

I haven't actually used that Perfoverlay so I cannot tell you how to interpret the graph properly but given that my bf4 has been sluggish lately, I might need to play with it tomorrow. If you are still stuck for what to do or how to interpret, I will try to help out.

In the mean time, make sure that your computer is clear of dust (all vents, fans, heatsinks, etc) and that your computer has unimpeded airflow at the front and back - that hot air needs to go somewhere and if the airflow is impeded too much at the back then it will warm up very quickly. If your case air flow isn't too flash then you might be running into thermal throttling on the gpus or the cpus.

And thing happened to me when I used sli 780s. I saw no performance increase whatsoever. For me, it was a bad psu and a cpu bottleneck. I think your psu is fine, but I had an fx 8350, a little more powerful than yours, and was getting even worse fps than you lol. But eventually, I sold one 780 to pick up an i5 4690k and a decent power supply, and my fps even with a single card never goes below 80 on ultra 64 man conquest servers. Hope this helped a little bit.

This is bullshit i have exactly the same build and exactly the same problem. Its the games fault something is messed up because bf3 runs at 100fps. According to cpu benchmarks there is no differance between an fx 4100 and an i7 3970. http://www.techspot.com/review/734-battlefield-4-benchm...

This is very annoying...-_- I know how you feel my rig easily gets 60-100 frames with drops to 50 fps on crysis 3 on very high...... Dice please fix this

I'm just gonna let you know, that cpu is nowhere near the computing power of the 3970. Maybe in a single player game. But other than that, 4100 is a low end cpu. All of the fx CPUs are going to bottleneck cpu intensive games, they just don't have the power that mid range i5 and i7 CPUs have
