Well, we can certainly help you, but we'll need quite a bit more information:
1: Where are you buying? (country and state/province needed, city ideal)
2: Do you need peripherals, a monitor, and/or an OS?
3: Do you wish to overclock?
4: Is gaming the only intended use of the system?
5: How do you feel about CrossFire/SLI?
6: Do you have any other requirements regarding the system (needs to be silent, needs to be portable, etc.)?
Answering those questions will help us to help you.
