I am wondering of ways i can customize my current Alienware Aurora R5 cpu, right now It has 4GB RAM which I intend to keep, an Nvidia Geforce 9600gt graphics card which I really want to change, and an AMD Athlon 64 X2 5200+ dual core processor which i want to upgrade. I dont want tobuy something to then find out that it will not work with my pc which is why i am asking the community. Help me please!
