So I have a HP rp5800 computer that runs on windows xp professional. A friend gave it to me so i do not know if it has components since it was bought or if it was modified. He does not know either for some reason. Anyway, the graphics card is Intel HD Family 2000 or something, and it has a memory speed of 256mb. I would like to know what graphics cards that are at least 512mb ones that are quite cheap, and also compatible with the PC. I would like to play my games....BUT THEYRE TOO SLOW
