Only thing thats changed is the Graphics Card, upgraded (if you can call it that!) to a 8600gs after the 8400 failed.
I know that upgrading the graphics, memory etc would probably give it a boost but what i know nothing about is motherboards, quad core processors etc etc and really could do with some expert advice in that department! Would i be limited to what i could buy and upgrade?
As you can probably tell after reading that i could do with all the help i can get!
