970 problem? Help

[killzone141]

I've noticed in single player games i'm using 98-100% GPU usage but in games like battlefield 4 on multiplayer i'm getting 70-100. The strange thing is on single player battlefield 4 i'm getting 100% constant.
Is something wrong? or is do i have to wait for a new driver from Nvidia to fix this?

CPU is at 80% on all cores and im running amd 8320 at 4.3GHz. My PSU fan seems to ramp up when im playing single player and its hitting 100% on gpu. So maybe its the PSU but dont understand why in single player its fine and multiplayer, usage goes down

ok so i put my cpu to 4 ghz and turned down the volts to stock and its improved abit. even on battlefield 3 its about the same issue. So its either the PSU or some how im bottlenecked by the cpu even though its not at 100% usage doesn't make sense in my head. i got a 630 watt termaltake, its bronze certified. I'm gonna buy a corsair 800w. see what happens

now i have underclocked my GPU and its stayed the same usage. I'm certain its the PSU now
