I can see several potential problems here. First, trying to edit GoPro on anything AMD. You should seriously consider an i7 3770K or an i7 3930K for such media. Second, you have 92 processes running. An edit rig should have maybe 40, 50 tops. Third, 8GB is pretty low for complex projects. Adobe tools will save some memory for other things, they won't use it all, so upgrading to 16 or even 32 might not be a bad idea.
Ok, I understand on the CPU and the Memmory, I'll update the memory, but the CPU, that will have to wait.
On the Processes? 40... Well I rebooted the machine and let it Steele for 15 minutes... It is sittings at 0 on CPU and 1.8gb ram used... But without doing anything there are already 76 processes running? Nearly double and I have not loaded a single application yet.?
That just means you have too much crap running in the background. Like it or not, these days an editor really does benefit tremendously from also being very knowledgeable about computers themselves. By that I mean building your own computer with parts, installing Windows yourself, along with only what's necessary for editing. General purpose computers often make for a less than ideal editing experience.
So...I recommend wiping your hard drive and starting over by installing Windows from scratch if that's never been done. And if it was done recently by you or someone knowledgeable about edit systems, than take a look at all those processes and determine if it needs doing again, or if you can get away with simply Uninstalling some programs.
Either way, it means becoming knowledgeable about computers and software.
There are numerous web sites that provide guidance on optimizing a windows installation, that is, what to turn off, what to remove. Most of this doesn't require editing the registry, some does. Back in Windows XP days, I had a downloaded application that was named "ENDITALL" which when activated, would go through and stop processes that were not related to windows. It will skip processes it cant identify, but you can then tell it to kill those too, I never tried this on Windows 7.
If you are faimilar with the registry, in the user---microsoft---windows---branch, there is a sub folder labeled "RUN" and "RUN ONCE" this is where install programs add keys that force a process to start up on windows startup. Don't confuse this with the windows explorer "STARTUP FOLDER" You know all those annoying windows that pop up to tell that an update is available for a program (not the windows update)--they are all associated with a process started by the registry entries.
The more programs you install on your editing bed, the more of these you are going to have. Many of the posters on this forum advocate limiting you editing bed to editing.
For example, if you load real player, there will be processes started to activate the tray icon, and another to remind you of updates. Virus checkers do the same thing--but they are clever enough to also start a process that will re-install the registry key if you delete it.

You realize that your performance window is only showing CPU load and memory load. If your HDD are not up to the job, the cpu and memory could be waiting on disk writes to complete. i.e., it isn't using 100% of cpu because the HDD can't keep up with that.
