Graphics card upgrade? Is it possible?

[PeregrineX]

Hello, I am looking at upgrading my graphics card/RAM, and I was wondering if it was possible. Here are the specs: (PS, I'm away from home, so I don't know the exact specs, I will be back on Sunday)

2GB RAM
Intel Processor at 2.0GHz
Intel 4 Series Graphics

I found a used Radeon 7950 on eBay for $50, so I was thinking of buying that and 4 GB of RAM. Is it possible?

Well it really depends, we need some more specs on your PC.

I recommend downloading Speccy, reviewing the information and posting it here for further assistance.

As I said, I'm away from home, so I can't use speccy at the moment. However, I have figured out the model so I can give you a full report. Here it is:
