I've just bought a GTX 780 ACX, and the GPU usage is always under 99%... like 50~80% And in games like gta iv it stays at 30~40% gpu usage. Can it be caused by a bottleneck of my i7 2600k? it is at stock speed (3.4gHz) and i can't overclock it due of my motherboard chipset.

My Specs:

- EVGA GTX 780 ACX (stock speed)
- i7 2600k 3.4 gHz (stock cooler)
- ASRock B75Pro3m Motherboard
- 10 Gb RAM 1333 mHz (4 Sticks: 4gb/2gb/2gb/2gb) (2 Different Brands - Same DRAM)
- PSU TX750M Corsair
- HD 1 TB

*VIDEO:
- I've uploaded a video to provide more details about the problem:

- Notice that in games like Battlefield 3 the GPU usage is normal (99%)
- But in games like GTAIV the usage is low (35~60%)
- Also notice that CPU usage is low like the GPU usage, so I think that the i7 2600k is not the problem

I assume you have the latest drivers installed? Also is your bios up to date?
