I have a inspiron 570. I bought a phenom ii x4 965. Also I got some corsair memory card 1333mhz 4x2gb. Idk if I should add more or get more ram than my computer says it can handle I have windows 7 64 bit. I bought a 600 watt psu. Trying to upgrade my graphic card to the best it can support. I want to know if I need to buy a new case or get more fans and what kind of fans do u recommend if I use original case. I'm going to overclock my phenom ii x4 965 and maybe graphics card too. I haven't installed my phenom yet but I want to know which fan will be compatible with my case. If u know a good graphic card but it won't fit on my mobo or case and it's Compatible with the phenom ii x4 965 let me know cuz I might get a new mobo and case and use same 570 components.
