I just built a new system that for some reason on 3dmark vantage and battlefield 3 the gpu usage jumps from 99 to as low as 50's. I don't think this should happen with my new system and I'm pretty sure it didn't happen with my old 2500k with my 480's

CPU i7 2830 @ 4.7ghz
GTX 480 SLI @ 800/1600/1880
rampage iv extreme motherboard

Alright so I have tried a few different things and I also ran the taskmanager so I could tell what my cpu usage was and it never goes above 40% in bf3 so I don't think it's a bottleneck. Tried the following.


1. 3 Different drivers
2. Clean install of windows on another drive
3. Different Bios
4. Different Video Card slots
5. 16x/16x & 16x/8x
6. Motherboard drivers
7. Different Sli bridge
8. Turning the pci-e slots i'm not using off.
9. Disabled HyperThreading

So far nothing is working, I ran these in my old build 2500k@ 4.6 and I never dipped below 80fps in bf3 with everything on ultra. Now I'm hitting 50's & 60's with gpu usage dips of 50's.

**btw I already posted this in the cpu section of the forums last night but not getting any replies so i thought I might get some help if I posted in here**
