Desktop screen tearing and other seize ups. Graphics Card or Mobo or CPU failure?

Ok, I simply can't tell if this issue is for my CPU/RAM/MOBO or my Graphics Card. Anyways, everything has been slowly getting worse. Images and webpages load slower than before, it's a visual thing. But It could very well be either the graphics card or some other hardware. I can't tell if it's a proccessing power issue or a drawing of graphics. Anyways, it's getting worse so that in games like KF2 my game will seize up for a split moment when my camera will change distances, like zooming in on my weapon sights. Also the graphics seem to be kind of jittery when moving the camera around.

Everything seems to be worst when it's not been loaded previously. Any kind of new images or windows on my desktop are loading a little slower, but once it's there they interact just fine.

Perhaps because of all the image reference I should assume it's graphics card, but how should I really know? I need some help with suggestions on software that might help me diagnose my PC for any major hardware failure.

I've done a full reinstall of my Win 7 64 bit Ultimate edition. All fresh drivers and software, the issue has only got worse than before the reformatting, which I did to fix the problem.

I wasn't actually having any graphical issues in game before the reformat, but instead mostly when I was loading websites, especially those with a lot of images like online tv show listings or google image results, etc.

Thumbnails of stuff seem to load slower, I see the stages of the image, more stages than I should witness. Including some feeling I get of grayed bordering while transitioning.

Also, pages seem to take longer to load. As in I will see the internet page loading icon in the tab of chrome just circle longer than it should. That seems less a graphics problem and more of a processing problem. It's like instead of my 120mbps down cable, I have DSL or something.

Copy and pasting this here article into google docs as a safety save is also taking longer for the paste action to complete than it should. Again, I can't tell if that's because it's taking longer for the graphics card to write the pasted information or if the process is delayed because of the CPU.

I ordered a new EVGA 980 Superclocked ACX 2.0 from Amazon already, because I don't have the $900 I'd need to get a 5930k i7, 16 gb ddr4, X99 mobo.

Oh yeah, almost forgot to mention, I'm getting visible screen tearing on my desktop. Even just now moving the scroll bar from left to right and right to left on my Win 7 Volume Mixer, you can visibly see screen tearing in the volume indications area. I'm not getting screen tearing noticeable in video games, just on desktop. Most noticeable when I move a window back and forth between my monitors really fast. As a matter of fact, the other day I was entertaining myself seeing how many segment blocks I can make with a window while sliding it back and forth on my monitors.

Here is my current system specs.

Ok, I have tested my hardware with two monitoring programs. I also tried to install the VGA drivers for the onboard graphics of my mobo, then swapped my monitors to that. I did not remove the graphics card when testing the onboard graphics. I don't know that I need to remove the Nvidia card, let me know if I must do that to get a true test. Anyhow, the results didn't change. I was still having problems.

Here are the results of the hardware monitoring.
While monitoring, I was running a youtube video at 720p, a video clip from samples on VLC, 4 other tabs open, a couple of windows explorers open, viewing steam's store on steam, running both monitoring programs, teamspeak 3, while also playing Killing Floor 2.
Well, I figured out it's 100% not my video card. I uninstalled any and all things related to NVIDIA, especially the drivers, and then removed my graphics card, plugged the monitors into my onboard video, then rebooted. I installed my onboard graphics driver and things were still loading on web pages like they had been previously. I couldn't test in Killing Floor 2 because I guess the Intel HD drivers don't support it. Anyways, I canceled my order for the EVGA 980 SC ACX 2.0 from Amazon and instead placed orders for new CPU/Mobo/RAM.

I went with ASUS mobo, I didn't think to look at Gigabyte due to all the looking around I did confirming ASUS is solid.

Gotta have that CPU Cooler/Thermal Paste:
