AMD Radeon 7850 1GB Sapphire Low FPS Issues

Hello people! I really don't know what else to do, I have tried anything, I'm gonna explain to you from the beginning. One month ago I built a RIG to play:

Motherboard Asus M4A88TD-M

AMD Phenom II x4 955

8GB DDR3 Kingston RAM

1TB WD Caviar Black

AMD Radeon 7750 1GB GDDR5

PSU Antec 620W Pro

Windows 8 Pro 64 Bits

Latest Drivers from aything

The thing is there was low FPS in ALL GAMES, including Mortal Kombat Komplete Edition at 720p, AC4 and CoD Ghosts. When I say low FPS I mean really low, 15 FPS at gameplay and low settings.

I updated my Mobo BIOS, and the problem was solved, nevertheless it started to appear again.

Two days ago, I changed my video card to AMD Radeon 7850 1GB GDDR5, and STILL problems persists, I can't play decently any game, I uninstalled the drivers and re-installed even the beta versions, and I cannot even fight on Mortal Kombat whis is depressing.

DirectX is also up-to-date. What else should I try to do? Please help, I'm going crazy with this

  1. There will be two power connectors for your motherboard, the big 24 pin connector and another 4 pin connector that is in another spot on the motherboard. Are they both connected?
    The 7850 will have a PCI-E power connector, is this connected?
    Is the CPU fan running?
    Is the CPU heatsink correctly fitted?
    Are all CPU settings in the BIOS at default? Try resetting to "safe" settings in the bios.
    Check for a bios setting to monitor CPU temperature.
    Use task manager or perfmon to monitor processor usage while running your game.
  2. Everything is connected properly, I will reset BIOS to default settings and see what's up
    Temperatures are fine and fan is correctly fitted.
    This problema is so odd...

    Edit: I will check temps and performance on CPU while running Mortal Kombat just in case, giving this kind of issues always are about temperaturas and stuff!

    Well I managed to solve it, I reset my BIOS settings to default and everything runs good now, I really don't know what did I touch to mess it up.

    Anyway here some images:

    AC High FPS

    AC Low FPS

    Idle FPS

    Mortal Kombat High FPS

    Mortal Kombat Low FPS

    Tomb Raider High FPS

    Tomb Raider High FPS 2

    a) Is it normal Tomb Raider uses 99% of GPU?

    b) Is it normal AC4 Black Flag it's locked at 30FPS?

    Thank you very much for your time!
