So when i play youtube videos in HD, 1080p+ is where it gets really bad but 720p isnt exactly good either. I noticed when i go to another tab while the video is playing, the lag stops straight away, but when I go back to the video's tab the lag comes back...

when installing my new GTX 970 G1 I damaged some of the PCI-E slot on accident when installing, could this be causing this issue or is it probably something else?

I will be upgrading the motherboard after christmas but I would like to know if that is the cause.

Thanks
