Different mobo, lower results?

Here's something that has me perplexed. When Haswell came out, I built a new rig with an i7 4770k and 2x GTX 770's. Originally, it had a the Arock Extreme3 board, but I decided that board was a bit limited and a little buggy, so I swapped it for an Asus Z87 Plus. Much happier with the Asus, but here's the weirdness:

While I still had the Asrock board, I achieved a stable 4.4GHz overclock and ran 3dmark. I got a 12286 on Fire strike (#1 w/my hardware :)... now, On the Asus, I've got it stable at 4.5GHz, yet I'm achieving lower graphics scores (physics scores are slightly higher, due to higher OC I'm guessing) giving me a Fire Strike score of 11956.

I checked to make sure my cards were running at the same speeds for both tests, and they were. Literally the only difference is that the old test was on the Asrock board @ 4.4GHz, and the new test is on the Asus board @ 4.5GHz.

It's driving me nuts. Any ideas guys?
Thanks!!

Many possibilities.

One of them could simply be a driver-GPU timing/coordination problem. Try running at 4.4GHz on the Asus and see if that changes anything. If it makes things better instead of worse as would be expected, then you can be almost certain this is a GPU driver or software glitch.

Tried it but got even lower results :(

I've actually ratcheted it up to 4.6GHz now and I still cannot break 12k marks. It's maddening to think that the pathways and setup of the Asrock board might have just been better than the Asus board.... I like the Asus board so much more. Better UEFI, better features, more customization... I even flashed the UEFI to no avail.
