So I have my build all setup $750 after rebates and everything. But we're going out of town and I need to have it shipped to a friends house. So I put my billing address and my shipping addresses as the correct adresses(different addresses BTW). Now my question is will the mail-in-rebtes still work? will they be sent to my friends house or my house? can this invalidate me from the rebates? cause at $850 without rebates I can't afford the system if I don't get the rebates and will have to get a phenom II x4 instead of a 2500k!!!
