yup like mentioned danny just forget the SLI thing its a waste of money and not needed.
look at what thatguy done,he sold one of his crossfires to buy a phone
i would invest in a better cpu and mobo.
Im doing exactly the same as you mate in the summer,exept im staying with the same motherboard as its 45nm ready and im just buying 4gb of faster ram
as for my GT,theres no need to upgrade it yet same as your GTS.
