What would you like to know? Other than if I had to buy an AMD sysytem I would get one of the last Phenom II x 4 970/975/980s over Bulldozer it looks fine. Overpowered a bit for one graphics card and underpowered to add a second in Corssfire too. For what you have 500-550 watts would be fine and you need 750-800 to add a second card.
As much as I want to, I really cannot recommend the AMD FX series. There's a lot of both software and hardware issues related to it, and most motherboards including the modern 970 and 990FX don't support it natively out of the box.
