i need to know what board or what pro i need to make this all work.#hey i really need some help on this.Thanks.
You need a AM3+ socket Motherboard that will support that processor.
This Asus Motherboard supports your FX 9590 and is the LAST newest version for this particular model:
I have the same motherboard for my FX8350 but R2.0 and it has been excellent Motherboard and purchase. I have had it for over 5 years without any issues at all plus it is made with military spec components to make it last.
But most if not all AM3+ Motherboards are now considered to be End of Line or Legacy and not supported with driver updates.
If you don't like this Motherboard than google AM3+ Motherboards and you should get a list of different manufacturer Motherboards.
But before your buy a motherboard, go to the Motherboard's Support page and look at its CPU SUPPORT LIST. Make sure your FX9590 is listed.
Like the Asus I linked above: TUF SABERTOOTH 990FX R3.0 CPU Support | Motherboards | ASUS USA
The above is a partial list of the full CPU Support page.
According to the CPU support list only up to an 8350 is supported on the Crosshair v.
If you can find one,this board supports the 9590
