I'm having an issue where during my stream (or even when I'm not streaming and watching YouTube videos) the computer will "stutter" causing the video to lag/go choppy for 3 - 5 seconds and the sound makes a weird slowed down dragging sound.

Here are my specs:
CPU: intel i3-2120 3.30 GHz (2011 release)
GPU: Radeon HD 4850 (2008 release)
Memory: 16 GB
Win 7 64 bit

I was thinking of upgrading to a Radeon R7 250X or maybe a Radeon R7 260X for the extra $20 is worth it.

Will I see a significant performance boost in my stream? or will this fix my video issues when not streaming and watching YouTube videos? Could it be my video card is dying out,
