Hello everyone,I haven't been on this forum for long time. I had a good time being on this forum as there are very good specialists here. My m15x which is 12 years old still up and running. Problem is that my primary Graphics card burned long time ago. I have alienware m15x first gen from 2008 (pre dell machine) This model with exactly the some spec>>> https://www.notebookcheck.net/Review-Alienware-Area-51-m15x-Notebook.8835.0.html
I upgraded hdd to ssd and have 4GB RAM running Windows 7 64bit. The problem is when I try to play YouTube video from 720p or higher resolution video is gliching, it is not smooth. The secondary Graphics card Intel GMA
X3100 does not manage this video resolution. I would like to put some primary Graphics card to my old m15x. The question is what graphics card could I Install in my old m15x?

I don't think this video card will fit into my m15x?

 

I would personally avoid Nvidia cards, there is an issue with the M51x where any Nvidia driver newer than a particular version will lead to a BSOD. I think this was version 186.81 which is now 11 years old. AMD/ATI cards should work with a more up-to-date driver. The HD3870 is probably the easiest to find and most compatible. I have seen some get a HD4850/70 working BUT it requires a particular variant of that card with a compatible VBIOS. Up to you if you want to go through the trial & error.

 

Thank you for your answer. I think to go for this one>>> https://a.aliexpress.com/_m0uDuA7

 

That's says both HD3470 & 3650. I would avoid that listing personally. This listing is not much more $$, is more powerful, and came from an alienware.

Too expensive, basically i need main graphics cars so can use hdmi to send signal to TV. Do not need that expensive card
