graphics card upgrade help

Hi i'm new to all this and don't know alot about computers.I want to change the graphics card on my packard bell imedia 5093 so i can play games.I know someone who has done it on theirs and said they will do it for me but I don't know which one's will work.
How do i find out which ones will work for my system?Obviously i don't want to spend money on one then it doesn't work
Any help would be much apreciated.

That appears to have an AGP 4X/2X slot.

An AGP 8X/4X card would work but will only run as 4X.

In other words it is not worth spending for a good 8X/4X card.

You can get an inexpensive model that should be an upgrade over the 440MX that is in there.

You can also upgrade to 1GB RAM if you do not have that already.

Here is a Newegg list for what you are looking for:
