Can't Tell If This Would Be Bottlenecking...

Sorry for posting this again, but I did more gaming on BF3 with my MSI Radeon 7850 Twin Frozr and it seems to not be running at 100% with MSI Afterburner. Ok so, I go into the map Caspian Border and I set my settings to ultra. I look into the distance and get around 75% usage. When I move the crosshairs closer to me on the ground, it seems to go up to 99%. I do not know why it would be 75% at long range and not 99%. Is this normal? Here are my specs again.

My Specs:
- AMD Phenom II x6 2.9GHz 1055T (1yr old)
- 6GB DDR3 Ram (1yr old)
- 1.5TB Hard Drive (1yr old)
- 500W Cooler Master PSU (1yr old)
- MSI Radeon HD 7850 Twin Frozr (brand new)

I heard people saying that it could be the power supply not giving enough power. Is that true? Or is it just a bottleneck... I would love to give you any further information about this to help out.

Also I cannot get Catalyst Control Center to install, not sure if that would make a difference...

Found something new... my monitor is a 1366*768 monitor and that is what I tested the GPU usage on which was around 75%. I just went on 1920*1080 and it went up to 99%. It seems on my resolution I am not getting full potentialof the card. Any suggestions?

EDIT : Again I was testing resolution and I went to the lowest resolution which was 600x800 or something like that. It was running at 40% and was getting less frames than 1920*1080. What is going ON!!#!

EDIT 2 : Again I was testing and I was on my native resolution this time. I was getting 45fps on ultra and 55fps on low. When I went from Ultra to Low I had a 25% GPU usage drop...

Any help? Someone said that overclocking my processor would help the problem but I am not sure if that is the case.

Does it really matter if you're getting playable framerates at ultra in 1080p? Best your card has a lower % usage, actually, because then it'll probably last longer.

I would upgrade your PSU, though. Good 700w ones on newegg are dirt cheap nowadays.

It sounds to me like your card is just scaling its performance depending on the usage. My 6950 does that as well. So logically in 1080p it will use more power than 768p.

Is there a reason why it does this though? I would want as many frames as possible and if I were wanting to limit the usage of the card I would just put VSync on.
