Persisent FPS-stuttering

So I am taking my time to write up this issue in case anyone have any idea what is actually going on. What happens is that no matter what game I am playing, be it Battlefield, WoW, League of Legends, Super Hexagon, Skyrim, Starcraft, you name it, I often experience an irritating FPS problem. It does not matter if I am in an epic firefight with tanks bombarding and jets roaring overhead, or if I am chillingly fishing somewhere in Northrend by myself.

The best way I can describe it is that my FPS is 'stuttering', not bad, but enough to be annoying. If I were to try and impose my FPS onto a graph by hand, since I have not been able to capture the actual drop in fps, it would look something like this:

I have been having this FPS issue since I got this computer several years ago, but since then, I have upgraded and replaced everything, video card, RAM, the motherboard and power supply. The only thing that is as it once was is my HDD and my CD-drive, but I know that i't cannot be the HDD because I installed an SSD last month and have been playing several different games from it, without the issue going away.

Some days are better than others though, and I dont know if it has anything to do what I am running in the background, but some days I dont even notice the issue while other days is unbearable.

I a have a theory that it is not just the FPS going down, because in some games actual effects are being delayed (such as smoke coming from a rocket missing in places whenever the issue sticks fourth it's ugly head)

I see myself as somewhat of a veteran when it comes to dealing with strange and unusual computer problems, so I am not the kind of person that doesnt know to clean the cabinet (which I have done several times before someone asks) or doesnt know how to open the DX-diag.

My setup is as follows:

OS: Windows 7 64-bit
CPU: AMD Phenom II X6 1055T Processor, ~2,8 GHz
Motherboard: Gigabyte 870A-UD3
RAM: 8192 MB (2x4096 Kingston 1600 MHz)
Graphics Card: XFX Radeon 6950
Power Supply: 750 Watt
Resolution: Im running on a 23" monitor on a 1920 x 1080 pixel resolution.

All drivers are to the best of my knowlegde up to date but if needed I can easily provide a dxdiag output.

If anyone has any idea what is going on that would be incredibly helpfull. Thanks in advance!

 

It's happening both online and offline. Heavy CPU games tend to be worse tough. Ill try disabling just about everything and report back.

 

That looks like the stuttering problem that affects the high-end ATI/AMD cards and Crossfire setups, ATI are aware of it and should be offering an updated driver in the next month or so.

 

Wow, really? I thought I had researched enough to start asking for help! If it is really that simple then whatever I do it won't help, right? I did try to turn off everything except for MSE and booted up Rift, and then just let it sit there. The stuttering slowly started after a couple of minutes.
