Dell Precision M2300

Hi all. New to the forum.

I was hoping someone could answer a question for me about the Precision M2300. TL:DR is in bold. I currently have a Latitude D630 that actually gets quite a lot of use for work as it runs three different operating systems and has an RS-232 port. Obviously I am not gaming on it or anything crazy like that because of the poor graphics. I only have two issues with it and I suspect both are because of the poor graphics capability by today's standards. The first issue is that YouTube videos get a little jerky when viewed in 1080p (dropping down to 720p makes everything work normally). The second issue is that the overall GUI in Windows 10 gets a little jerky as well (but this is mainly limited to the Start Menu). Other than that, everything actually works absolutely perfect.

I have an opportunity to get a Precision M2300 for cheap. As I understand it, these are identical to the D630 except for their far superior graphics (relatively). Does anyone have a Precision M2300 running Windows 10 that can check 1080p YouTube capability? Is it jerky or is everything smooth? If the graphics of the M2300 are superior enough that it doesn't have the "issues" I am having with the D630, I will probably pick it up and devote the couple hours or so it will take to transfer everything over to it from the D630. But if not, I will probably not even bother. Thanks for your time.
