Hello,

With the recent 780gtx price drop i decided to get a second one (mainly because i had been very satisfied with my 570 SLI in the past)

On wow i'm getting 48% usage on both cards, wich is alright for flying around and stuff but once i get into a raid my fps drops to 15-30 while both cards still sit at50 ish % usage. My CPU is an i7 2600 running at 4ghz and its sitting at 15-20% usage so its not like its holding anythingh back

Same goes for battlefield 4, cards sitting at 60% usage aswell as the cpu and i get an average of 30-40 fps on both 1920x1080 and 5760x1080. vsync is off, power saving in the nvidia controle panel is set to max power...

anyone know what could be holding it all back?

What PSU do you have in your system?

Coolermaster Silent Pro 1000W, also what i forgot to mention is that when i run firestrike on 3dmark the usage doesnt go over 70% either even though its set to 106% on evga precision.

Are you sure you're usling the lavest driver?
http://www.nvidia.co.uk/download/driverResults.aspx/688...
This is the newest certified driver, it aids 12% extreme performance with the 780 in BF4. Also, if you haven't installer drivers after late october, they won't have the BF4 SLI profile yet.
Have you configured the drivers probably?
Try maxing out every setting @1080p with a single card. Should get very good fps. After, try adding the second card and see what happens.

I am using the latest drivers and it's not really just bf4, Also have been using a single 780 for the past 3 months since I only got the second one a couple days ago and i'd say the performance hasn't changed that much. I guess i could test them both sepperatly to see if either of them acts weird.

Yes, please try doping that. You might have a defective one.

I blame drivers and furthermore BF4 is really buggy at this time. Run Unigine Valley 1.0 comeback and tell us about the GPU utilization!

FPS:
99.1
Score:
4147
Min FPS:
34.0
Max FPS:
152.1

Setting:
Render:
Direct3D11
Mode:
1920x1080 8xAA fullscreen
Preset
Extreme HD

I guess these scores aren't too bad for stock cards however,
GPU-Z said my clock was at 1019mhz, and +/- 95% usage while on evga precision my core clock was still at base clock showing 60% usage so i'm guessing evga precision is kinda useless.

So both WoW and BF4 scale bad with 780SLI i guess?

You really need to overclock your 2600k to at least 4.5-4.6ghz to alleviate some of the bottleneck. How much RAM is in your rig and are you using the latest version of EVGA Precision with lastest Geforce drivers??

I dont get how my cpu is bottlenecking while i haven't seen it go over 60% usage ever, I have the same issue with afterburner that it doesn't monitor the core clock mhz correctly, thats why i switched to evga precision (4.2.1) in the first place. GPU-Z seems the most accurate for me. I got 3x 4GB DDR3 Kingston 1334mhz + 1x 2GB DDR3 A-Data 1334mhz and the drivers i'm currently using for nvidia are 331.65

I did run another unigine valley with the cards running at 1200mhz and got a lower result so that did point out in a cpu bottleneck i guess

Yes, you should overclock it to about 4.5

For your reference, I have a i5-4670k @ 4.2 GHz with two 780s at 1044 MHz. Modest overclocks, but I score relatively close to your Valley benchmarks on Extreme HD.
FPS 107, score was 4477, had a peak of 188 FPS.

WoW was never really written all that well, so it's just poorly optimized. On the other hand, your BF4 FPS doesn't make sense.

I'll average anywhere from 150 (on small maps) to 110 on the large maps, Ultra, no MSAA. With MSAA it's an average of around 110-100.
