Is it normal that GPU usage on my 7770 with Q8400 @ 3.1 GHz is around 30% when playing Battlefield 3 or Battlefield 4 multiplayer.
That is really annoying.
I have 4 gigs of RAM if that means anything.

Also in singleplayer games, like watch dogs, Assassin's Creed 4, GPU usage is low. About 50% max. Is this normal??

If the CPU usage is that high, it does indeed appear the CPU is bottlenecking the gfx card. (???) But the Radeon HD 7770 should not be fast enough to cause a bottleneck to even that older quad core at only 30% usage. I imagine this is on busy 64 player servers when this happens. Does this happen if playing offline too? Let's clear up anything obvious first.

Run CCleaner and have it do the Clean and Registry sections both. https://www.piriform.com/ccleaner
That will eliminate most resource-wasting crap and registry errors.

Then check your System Config/Start Up and see how many pgms are set to start with Win7 and run in the background. Uncheck as many as you feel comfortable with eliminating. You can always put the checkmark...

In Battlefield 3 and Battlefield 4 (both multiplayer) CPU usage varies between 90% and 99%. Most of the time it's over 95%, so I can say it's pretty good. CPU is clocked at 3.1 GHz, but there is no difference between 2.67 and 3.1 in GPU usage. GPU usage in BF3 or BF4 is mostly 30%, maybe 35-ish. Could it be due to low voltage coming to my graphics card from PSU?

You can always put the checkmark back in later. Here is some help figuring out what each item does: http://www.pacs-portal.co.uk/startup_search.php
Look in the Command column for everything that is following the last "\" in the command. Type that in the dialog box.

I've also tried Grid Autosport, and CPU usage was around 70%, GPU usage from 60% to 80% (depends on camera - cockpit camera had higher GPU usage)

These are benchmark results from game. High preset and 4x AA

Also take a look at my voltages and temperatures here:

(screenshot taken while in-game)

I think that temperatures are normal, but what about voltages?

The Grid Autosport results seem fine with the CPU and GPU usage. About what I would expect. The GPU and CPU being pretty well balanced.
Your benchmark also looks great for the CPU and GPU you have... depending on what the resolution was.
Your temps look good too. But I don't trust the voltage readout in HWMonitor. No way your system would stay running if your +12V rail was that low. So that makes the other voltages suspect.

Yes, my +12V rail is THAT low. Just look at my OCCT power supply test results:

It's not even close to 12V, and I suspect that low voltage can cause bottleneck, and because of that my system doesn't run as well as it should run.

Yes. But it depends where that +12V reading is being taken at. I would check at the 24 pin connector with an accurate Voltmeter while the system is loaded. If the reading is low there, that would indicate the the PSU is at fault. If it is normal there, that would indicate that the reading is taken downstream from the 24 pin connector. Possibly at the VRMs. That would be my hunch. Because if the rest of the board, the drives, etc were receiving only ~8 volts, the system wouldn't run.

Use the pin-out above to read the +12V value between any black and yellow. You can probe the connector from the back while plugged in and running.
