Pzerofgh is right, the FX-57 isn't worth the money, get a 4400+ dual core or an Opteron if your into overclcocking, and grab yourself a X1900XT or wait till the G71 but that might be 1-2 months away assuming everything goes right. Don't go with PSUs that come with cases, 450W is kind of low at this time. I would go with the 90 dollar Antec TruePower 2.0 550 Watts off newegg (make sure you get the 90 dollar version instead of the 100 dollar version like I did but it still works with my ATX mobo).
I would go with the DFI Lanparty Ultra-D motherboard.
