I have a 2005 dell xps 600 gaming computer with a Intel Pentium 4 3.0Ghz cpu, 4 ram slots and currently a nividia GeForce 6800 graphics card. And my motherboard says sli ready on it but i don't know the model number of it. Anyone know if i can upgrade to a core 2 duo cpu without changing motherboards ??? Trying to meet minimum requirements to play W.O.W. without buying a whole new computer ATM. Any info? Plz.
