I just upgraded to the Z87 Classified from the X58 HYDRO, both boards are EVGA.
 
I spent the money to build a faster system to help me with my video/photo processing and electronic circuit simulations. I am an Electronics engineer for LG, shoot and edit videos/photos for CBS MaxPreps, and I do play computer games.
 
I was told the new Z87 system would be much faster than the X58 system.  Perhaps, I was told wrong.
 
My problem is the new system is slower in bench mark testing and in real usage.  In comparison, the new Z87 system takes longer to process large video conversion files (regardless of video conversion programs or formats) and longer to simulate my electronic circuit designs.  When I compare the two different systems in 3DMark Fire Strike, the results for the new Z87 system do report slower than the older X58 system.
              
So, I asking for Bios setup suggestions to get the new system to run correctly/faster, or an honest detailed answer to why the new system will always be slower than the X58 system I had built.
 
Old system:
X58 HYDRO Classified,
Intel i7-975 Extreme @ 3.7 MHz water cooled,
Corsair Dominator GT 2000C7 CMG6GX3M3A2000C7 with fans,
EVGA GeForce GTX 770 SC w/ ACX Cooler
 
New system:
Z87 Classified Intel,
Intel i7-4790K @ 4.3 MHz water cooled,
Corsair Dominator Platinum CMD32GX3M4A2133C9 no fans,
EVGA GeForce GTX 770 SC w/ ACX Cooler
 
 

I have tried XMP memory and manual settings (factory Corsair setting).
 
I did try the XMP settings with default CPU settings and overclock settings.
 
I have tried both default CPU settings and a 4.3 overclock setting---slower with default CPU setting.
 
No faults in Prime with any combination of Bios settings.
 
No combination of the aforementioned settings gave me faster results at or above the X58 setup.
 
I currently have the Bios set with XMP for the memory and have default CPU settings. 

The X58 has the triple memory configuration which has far better memory bandwidth. The X99 motherboard and it's applicable CPUs is the correct upgrade path for a replacement (after X58 and X79).
 
I assume you have the latest Z87 BIOs installed as well.
 
There could be something I've missed so I'll try and refer this to EVGA tech support and see if they have any info for you, provided they have time to reply to this thread.

Good morning,
 
Just for my own curiosity, any reason for the overclock being set to 4.3 when it can turbo to 4.4? With the GTX 770 is this the same video card you are using to test in both systems? Personally I don't feel this is going to a be a CPU issue due to the Physx score. What it comes down to is the graphics performance. If it's the same video card, the question of the hour would be: why is it performing higher on the X58 than the Z87. Do you remember what the 770 boost clocks were in both systems?
 
*Update* I can post my results for 3D Mark but i'm using two 780s on a Z97 Classified. The score comparison is going to be way off. 

4.3 is the speed 3DMark reported with the default Bios settings of the Z87. So thats what speed I posted up.

I know the turbo is 4.4 speed, but its never been reported by 3DMark that the CPU has gone higher than 4.3 with auto settings. If I overclock, then 3DMark will report exactly the speed I set. I have gone 4.7 but have it back at stock settings till I figure out why this new systemIis slower. Yes, 3DMark did report the 4.7 speed.

My video boost clocks were at stock settings in both systems, and yes... I did have the same video card for both system's bench marks.  I thought EVGA took down the newest overclock software. Or is it now available for download?

Don't worry about posting your speed results with a different set up. Thanks anyway.

I have the video card in the #2 slot from the top.

Thanks in advance for your help.

Again, the video card is in the 2nd from the top slot. 16x slot

Yes, a fresh install of Windows 7 64 bit on the SSD. SSD reported 535,000 & 562,000 speeds on the Z87.

For video editing I use Adobe Premiere Pro CS6 and Cineform Prospect 4K & some other plugins too.

For photo editing I use Adobe Photoshop CS6, Adobe Photoshop Lightroom 5, and Canon Studio Solution and some other plugins too.

I now see an an improvement of the video conversion time if I do NOT have a window open showing a preview of the converted video. It shows in real-time.

The X58 system was faster converting the video files WITH the preview window open, the Z87 is much faster than the X58 if I do NOT have the preview window open

I'm guessing, something with the video card, video drivers, Bios setting, or motherboard is going to be the issue. Right?

I did remove/install the video card and do a clean install of the video card's newest driver, but did not improve speed report in 3DMark.

Shouldn't the video card work faster on the Z87 when compared to the X58? Or is it the same or slower?

Thank you in advance for your help.

Video card needs to be in the first PCI-E slot. Install the same video drivers you were running on the X58 system.

 
 
I did not know about "NON-BUMP" policy here.  Thanks for the heads up and I wont do it again.
 
I did try installing the video card into the 1st slot and 2nd slots, and the test results were exactly the same for both slots.  In Bios, I would see 16x for the PCI when the video card was in either 1st or 2nd slot.  So, that was OK.
I did a CLEAN install of the video driver 3 different times, and each time the test results were the same.  So, that was OK.
I ran several different Stress-Tests (video and CPU), and each time the tests did not report and issues (the 1st and 2nd slots passed similarly).  So, that was OK.
I did try a friends same video card in my computer, and the tests reported the same.  So, the video card was OK.
 
Once upon a time, years ago, in the EVGA motherboard forum:
Users would post up their bios & windows settings to get help,
Users would be able to view other users bios & windows settings to help others,
It would be easy to find out what each Bios parameter/option specifically controlled.
 
I don't see user's system settings (Bios & Windows) or explanations of Bios parameters posted like it was in the past.  Is there a "NON-BIOS-POST" policy?  I'm not finding posted Z87 Bios settings as I did experience in the X58 motherboard forum back in 2009. 
 
I have had a few eager and knowledgeable users tying to help me, and I do greatly appreciate all the replies.  Thank you.
 
Anyway.... after a full week of tweaking the Bios, Windows 7 64, and NVIDA settings... I did find a combination that worked for my Z87 setup.
 
Example, 3DMark Sky Diver, Z87 Classified:
Results before---15,052.
Results after-----21,442.
28.9% Improvement
 
Example, 3DMark Fire Strike, Z87 Classifed:
Results before---6,579.
Results after-----7,278.
9.6% Improvement.
 
The CPU results are all the same in both Sky Diver & Fire Strike tests.  The Video card results are vastly different in both tests.  The setting for the CPU/Memory/Video card are all at STOCK settings for each component in the BIOS and in Windows 7. 
 
So... now the new Z87 Classified setup is faster than my X58 HYDRO Classified setup. The results are NOT as high as I had expected over the X58 HYDRO motherboard.  Currently, I'm wondering that I should of purchased a $40.00 SATA  III card for the X58 (for new SSD), because there is less than 10% improvement (stock Z87 vs stock X58 HYDRO) for the $598.00 I just spent for a new Z87 system. 
 
I will start to overclock my new setup and I hope to improve the speed results to higher reports.
 
Thanks to everyone that posted up to help me find a result to my issue.
 
Too bad I lost a week of time trying to resolve this simple setup issue.
 
Again, I do greatly appreciate all the replies.  Thank you! =)
