I upgraded my system, and the "underperforming problem" of my R9 280X was due to the AMD Phenom II X6 1100T Processor, it was bottlenecking the R9 280X so it could not perform as it should/could.
I now have a Intel i7 4790k @ 4.4GHz (stock turbo) with an ASRock Z97 Extreme6 Motherboard.
Right now, in EVERY GAME, I get 98-99% GPU usage. Finally I can experience how this card is really able to perform.
If an admin reads this, please mark this as Solved.
It was a true bottleneck case. (even tho I thought not at the beginning.)
Thanks all of you who tried to help me, deeply appreciated.
