Questions about Hp Pavillon MOBO 500 series
 

HI guys,
Heres my problem me and my friend were trying to figure out what is the right kind of memory to put into this mother board, but the problem is we do not know the manufacuter and we looked all over trying to find it, we have no clue maybe one of you guys no what brand that hp uses or a website of some sort
One other question is i am thinking of buying a geforce 5200 fx 256 mb or a geforce 3 ti200 golden sample. Which onw should i get i will be using it to play Final Fantasy XI and other games that have the same graphical quality (ps i am poor college student so i couldnt afford much of anything else over a hundred dollars :( )
Thanks for anyhelp that yoiu guys can give me
