OK, thanks good. Both cards work excellent. 
Second is maybe little better for 5%. Now you know at least cards are functional. 
 
Did you thought when this finish to replace case???
Some where you can easier to install graphic cards.
With magnet screwdriver is not problem at all.
 
Look your Graphic Score in Firestrike on second card and mine, not main score because you have Intel Extreme 
I can't believe ...both 13.111
 

haha, nice score.

I thought to tell you before few minutes when I wait to see what is problem, graphic card, PSU or motherboard.
PSU would be easiest to replace... but if you need to explain ASUS this, better think how to do that, and explain shortly, you will need sedatives.
But don't give them to force you to pay another motherboard if 4 cards can't work as they promise. 
And look my score and your on second GPU is same. OK now would be few points more or less but...
Nice you got excellent cards... 
 
Don't forget to make MOD RIGS if you want.

 
Yeah man I guess if one good thing were to come out of this it would be the fact that it seems like both of these cards are "golden samples" from EVGA.  By themselves they got some pretty insane scores when benchmarked on air.  Sounds pretty crappy of me to say this but I kind of wished the second GPU was dead because it would be a lot easier to deal with EVGA and replacing one GPU than it would be to deal with Asus and replacing my entire motherboard.
 
Not to mention the time I'll spend without a home machine...

Also looks like the fan on my south bridge is dead too.  Doesn't surprise me.  I always knew this stupid tiny little cheesy fan would die at some point.  Guess I never noticed it before when I was running crossfire because the cards were so big.

I go to play BF3, first time.

I have same fps as he, about 140-142fps MAX, about 68-70fps avarage and about 27-29fps min, and similar result.

My result is here...stock.. and I can't much better than that, maybe 2-3 points.

 
Example this is result of overclocked ASUS R9-290X reference with waterblock on custom loop.
As you see card is tight and tense as frog. And AMD say R9-295X is stronger than GTX780Ti SLI...
That's impossible... How can be??? Difference with more chips are only bigger on NVIDIA side.

 
And you see difference between GTX780Ti KPC and R9-290X is huge, but you have probably excellent sample of GTX780Ti SC.
I need only 30 points for 6.000 GPU Score in Firestrike Xtreme on 2560x1440 resolution on 1200MHz boost and 1750MHz memory
...2200MB Video Memory Usage If I saw good.
I could achieve 6.000 that with better processor than i7-3770K. 
6000 GPU Score in Firestrike Xtreme 2560x1440 out of box can't achieve many models today. 

I figured I'd update you guys on the situation at hand here.  Truth is this issue has been getting on my NERVES this past month.  BADLY.  I called up Asus the day after my last post and they told me they needed the serial # for my board.  The tech told me to look by the 24 pin power connector for the S/N.  Needless to say he was either 1/2 braindead or looking at a picture of the wrong board because it was on the back of the board.  After speaking to him for 20 minutes he actually thought that I was talking about a graphics card for a while.  In order to prevent me from taking my entire PC apart he tells me to look in the BIOS.  It wasn't there either.  Then he tells me to look on the box...
 
Problem was me and my dad had our boxes in the same spot and I couldn't figure out which one was mine and which one was his.  I took him I'd call him back... hung up... and ripped my PC apart and copied down the code.  He told me I was eligible for an advanced RMA (because it's a pricey board I guess) and it was obvious I knew what the problem was.  He told me he'd send me directions on how to proceed in the email.  He said it was A-OK for me to hook my PC back up... so I did.
 
Next day I get an email:  "Unfortunately, the APS Advance Replacement RMA Service you requested is not available. We are still able to provide regular RMA service since you are still in warranty".  I called back and explained to the guy that I cannot under any circumstances be without a PC for about a month.  Not only that I was told I could hook it back up and get an email the very next day basically saying I have to rip it apart again.  He assures me it would go through this time so I hung up and waited a few days.
 
The RMA request gets denied a second time.  This time I called REALLY mad and spoke with a manager who, after about 30 mins of explanation, told me he'd go into the "back end" of the system and put my request in again... whatever that means.  Sounded like manager talk for "I'll complain at someone and get this to work for you so you don't call extremely angry again".  I asked him how it was even remotely possible that Asus would not have this board in stock for me to get an advanced RMA but would somehow magically have one in stock once they got my board in the mail.  He said that "our factory doesn't have boards on hand so we have to wait to receive yours".  I said "I realize that but what sense does it make for you to be COMPLETELY out of the board I need in stock that's one of your best sellers?  You guys won't make one appear out of thin air just because I send in mine".  lol...
 
I've been running on a single kingpin for the last four weeks.  My performance with even a single card is absolutely atrocious.  I'm having my doubts that this is simply a PCI-E problem since I've been gaming with a single card for the last month.  It works and all... but my FPS tanks hard no matter what kind of settings, resolutions, or refresh rates I run at.  It doesn't matter which kingpin I run in the first x16 slot either.  The performance is almost equally crappy.
 
Thanks to those of you who helped me try to figure this out.
 
Edit:

Also, I believe I should have gotten four free games from buying two cards.  How do I go about doing that?

Curious, did you try and do a clean fresh install?

Okay so... please excuse my long winded post here... a bit of explanation is required for you to understand the extent of these issues.
 
I dealt with Asus RMA.  Boy... was that a PAIN in the butt.  Over 6-8 phone calls and about two months worth of emails back-and-forth to Asus and I was finally able to receive a replacement Rampage IV Extreme.  The board arrived yesterday.  Immediately I hooked up my rig, installing the second Kingpin card that I had to remove previously since my PCI-E slot was toast (south bridge was fried).  I ended up figuring out why my CPU was approaching the 80C mark when gaming and about 50C on idle.  My heatsink was coming loose.  I re-applied thermal paste to the CPU and re-installed it no problems.  It worked!  Only problem was that my computer was still taking forever to start up (after hitting the Starting Windows screen) and my benchmark scores were still very sub par.  Here is a screenshot of my unigen benchmark after I overclocked my CPU to 4.0 GHz. 
 
 
I tested it in firestrike.  Those results aren't even worth posting (they stunk). 
 
I decided a format was in order.  After all, I didn't format after getting the Kingpins originally and I could still have a driver conflict (even after sweeping the video drivers off my system).  I formatted.  My computer was still taking 5-10 mins from the "starting windows" screen to boot into windows.  The boot prior to this screen (BIOS splash screen) and after this screen (the actual loading of windows) is really fast... it's just that one little part that takes forever.  This is with absolutely NOTHING on windows and all hard drives disconnected except for my Agility 3 SSD.  I reinstalled my motherboard drivers (latest) and decided to do some testing in steam games to see if at least the FPS/benchmark issues were resolved.  They weren't.  SLI is enabled in the drivers (and recognized) but I'm still only able to manage 40-60 FPS in TF2 (with random jumps to 300 every once in a while) and about 25-50 in Rise of the Triad (that came with my Kingpins for free).  It's important to note that when benchmarking on these cards or gaming the clock speeds seem to be jumping up where they're supposed to but the performance is just terrible.
 
Anybody know WHAT IN THE WORLD is going on here?
 

Trabe, I've never had slow boot times with my Rampage IV Extreme.  It's only been this way since March or so when I revered back to Windows 7 from 8.1.  I am running the latest BIOS (Version 3901 I believe).  My computer runs just as bad when SLI is disabled vs enabled... I've already tried it.  I have not tested my power supply voltages (even though I do have a multimeter) because I'm not comfortable using a multimeter to check the PSU.  I've only tested outlets and things with it.  My cards are both running PCI 2.0 X16 (as you will see in GPU-Z).

I'm going on close to four months without a working machine.  Can't game well.. can't start up well.   I need this machine working properly before the end of August when college starts.
 
I'm going to post some screenshots here.  If anyone notices anything interesting please let me know.  I have a massive headache from this pain in the rear end machine.
 
Pic #1-  Bear with me on this one.  Although (like 90% of you) I take the Windows PC Performance Assessment with a grain of salt I did find it interesting that between when I originally ran the assessment with my old video cards back in March and formatting yesterday and today my CPU score went from 7.8 to 6.3.  I got the same score when I tested twice.

 
 
 
Pic #2-  Looks normal to me.

 
 
 
Pic #3-  Not really sure why this happened?

 
 
Pic #4-  Voltages (PSU is a Rosewill Lightning 1300W Modular as indicated in my signature.  Can anyone confirm these are normal?)

 
 
Pic #5-  Once again can anyone confirm the voltages look OK?  Temps look normal.  Except for I'm not sure why VGA 1 & 2 aren't getting readings.  Could be because the cards are monitored via NVidia software and don't work with AISuite?

 
Pic #6- Temps 2

 
 
 
Pic #7-  Same issue with drivers as above.  Never seen this before.  Not even sure it's possible this could be a related issue tbh.
 

 
Pic #8-  Speeds, clocks, etc.. appear to be okay on GPU-Z for the second 780ti.

Ah okay sorry will do that now.
