I found an old Hp A330-A350 around my house. I want to overhaul it to play games with good graphic output. definitely Total war empire and the newer Total wars. Any help on a parts list and and components that I will be able keep to use. My monitor is 19" but I am want to upgrade soon. Still not sure on the budget but of course any ways to save money would help. Thank you very much for all the help.
