I've been experiencing Youtube video stuttering on my desktop when I set the video quality to 1080P. If I set it to a lower quality, i.e 480P, the stuttering goes away. I'm experiencing this in both Chrome and Firefox. I doubt its being caused by my internet speed (300Mbps). I've got an SSD and the original i7 920 processor so I doubt those are causing the issue either. My graphics card is a GeForce 9500 GT (512MB). My guess is that the graphics card is causing the issue. Just looking for some input on whether you guys agree or whether something else could be causing the stuttering.
