Desktop GPU ugrade for Pavillion p7-1003w

[saseno456jp]

Going to start off by saying I know little to nothing about computer parts and that I don't have much money. Im looking for some cheaper GPU upgrade options for my old desktop. It is a HP Pavilion p7-1003w that I was gifted years ago. I didn't use it much but I want to play some games on it now. The main thing I want to play is persona 4 golden on steam, using can I run it, I learned my gpu needs an upgrade (everything else said what I had was fine). Here is a picture of the results https://imgur.com/a/KQLIfPBthe . Only thing i've changed so far was the psu, I now have a 450 watt. I was looking into getting a GT 710 but not sure if there is a better option. 

Any help would be greatly appreciated

Hello
your computer does not have a graphics card, indeed the addition would be a good thing
You can just search for what is recommended
or any other graphics card, which will be suitable for the power supply, and whose dimensions are not too large, compared to what can be installed
The only problem is that you have to look for old models, no longer too available.

In theory only old graphics cards
AMD Radeon HD 6xxx cards, or a Nvidia GT (X) 6xx card
can be used
on condition of having the required power supply for the chosen model
