Currently i have a integrated graphics card and I am looking to upgrade this to make Diablo 3 look better and be able to run on medium to high settings. I am looking at about $100-150 budget. PSU Upgrade is also needed if anyone has any reccomendations.
ATI Radeon HD 4200
6GB DDR3 memory
AMD Phenom II 840T Quad Core
Main question is can i buy a graphics card that is GDDR5 instead of GDDR3 and would it work?
