No obvious bottlenecks, but fullscreen HD videos choppy

[nibirue]

The Problem: When I watch a high quality video (720p+) in full screen, the video becomes very choppy. The audio works fine. I've done a lot of troubleshooting and testing out advice on the net, and the issue still persists.

Some Facts:
OS: Windows 7, Home Premium, SP1
Processor: Intel Core i7 2600 CPU @3.40GHz, 4 core
RAM 8 GB
Graphics: GeForce GTX 550 Ti, NVIDIA
asus p8z68-v pro MOBO
850W PSU
Internet connection is very reliable and fast. I get 50up and 50 down on average, and never drops below ~43 Mbps. The videos/stream are always buffered well ahead of the playback, so this is not the issue.
EDIT: CPU load is 14%, GPU load is 38% during a choppy video/stream.

Some things I have tried, that have NOT solved the problem:
- Updating drivers/Flash
- Disk Cleanup
- Defrag
- Anti-virus software
- Enabling Hardware acceleration
- Disabling hardware acceleration
- HTML5 Videos have the same lag
- Tried multiple browsers (chrome/firefox/IE)

I may have forgotten things I have tried, but the problem persists. If you have any solid advice, I will take it. Thanks

What is the processor load and GPU load when you are watching this?

 

[nibirue]

CPU load: 10 - 18% usage

Not sure how to check GPU load, though if you could tell me how I'll post it.

 

[bkoop]

I would download and try GPU-Z and see if your video card has any problems.

 

[ahnilated]

Yeah, GPU-Z would be what I would try.

 

[nibirue]

How can I know if there is a problem from GPU-Z? I've just downloaded it.

What does the load and temperature say?

 

[nibirue]

What does the load and temperature say?

Temp: ~35C
GPU Load: ~35%

It's too early to claim complete success, but it appears the problem is gone away. I'll update the OP after I test out a few other sites and qualities. Thanks for the help.

Streaming on twitch.tv was working fine but the youtube videos are still choppy.
