I also posted this on Overclock.net, I'm on the verge of re-installing windows again.
http://www.overclock.net/t/1507934/bad-performance-with-asus-rive/0_100I just purchased 2 EVGA 780 FTW to replace my 670 FTW on my second pc. I can't do anything about the 670 as one of the cards is being rma. Anyways my problem is I just noticed that the gpu usage during benchmarks are only mid 80 on card 1 and mid 70% on card 2.
I ran the same benchmarks on my main PC with the 780ti and both gpu's were at 90% or higher all the time. I called EVGA and they suggest I switch out the cards. I did that and the 780 FTW did fine on my main rig, constantly over 90% usage. The same issue I had with the 780, now I have with the 780ti, so it's not the cards, it's the motherboard? I checked the lanes and they're both running at 16X. I even took out my soundcard and no difference.
MY 3920K is OC at 4.7Ghz, so I'm thinking it can't be the bottleneck. I updated the bios to the latest one and no difference. I use the stock settings and no difference. I checked the temps on the cpu's and they were in the 50C on the H105. My systems spec are below, both running Windows 8.1.
Here's my firestrike score.

http://www.3dmark.com/fs/2594582This is the 780 with the Z97, gpu1 is at 96%, and gpu2 is at 97%

http://www.3dmark.com/fs/2606010Did a few test and it seems to be the cable and the input If I use the DVI-I cable in the DVI-D input, it gimps the performance. If I plug it into the DVI-I input, it's running at 96-98%.
EDIT: Spoke too soon, now it's back to being screwed up.

EDT: I found the problem, it's the nvidia geforce experience software. I took it off and things went back to normal, did a few reboots and things were still fine.
