Hello I am currentlly running a Dell Deminsion E521 upgraded to 3gb DDR2 AMD 5800+ dual core cpu rocketfish 800w psu and ATI HD4850 gpu. I am playing Old Republic and think I need to do something to improve my gameplay. The only thing I think I could change with current setup is add 1gb ram and swap graphics cards. It this going to improve my performamce or should I look into a new build? Also could I re use any of my parts like graphics card, power supply, hard drive or anything like that to save money on the build?
