I have had an inspiron N5030 for a while and I have a Intel GMA X4500HD graphics card. is there anyway I can upgrade? I am a little bit of a gamer, my games work fine for the most part but I've noticed recently that while playing, the game will freeze for a few seconds to a couple minutes at a time. I didn't have this problem until I updated my game. Should and can I upgrade my graphics card. How? Thanks for your help!!!
