64mb is my dedicated video memory, along with my VRAM, I do not know if I can upgrade my graphics card, I think I can install an nvidia card.
So you think I will not be able to safely run it?
If your Dell didn't come with an nVidia card from the factory, then you're out of luck, I'm afraid. Once you've chosen your configuration, whether on Dell's web site or in the electronics shop, you're limited to removing/replacing RAM modules and (possibly) the HDD. The CPU and any GPU are soldered onto the motherboard.
If I understand your situation correctly, your Dell doesn't have the optional nVidia card, leaving you with the built-in or
integrated graphics processer in the CPU, either HD 3000 or HD 4000. Even if you have the HD 4000 version, which might be able to provide graphics power comparable to around 1GB, I very much doubt it can handle the complex graphics of a computer game like Batman: Arkham Origins.
Historically, IGPs are only designed to allow users to open system applications without lag or blurring, although modern versions will also allow you to watch YouTube videos, online movies and play very basic games. PC games will generally require a separate or dedicated graphics card.
I think it's time to retire your 2009 Dell...
