get 3 msi twin frozr III pe/oc 6950s and unlock and over clock them to 6970s
this will give u 2x power than 580.
get a fx series cpu as yr requirement and 990fx - gd65 or gd80 .they have 2 x16 ports , i think both pci s run at x16 in dual mode.(correct me if i am wrong)
and ssd is only required for faster load times. like loading a map in a game.once the map is loaded then there is no use of hdd/sdd . so i dont recommend a ssd.
if u still want get a hybrid drive . and why do u want so large ram ? dont waste money .
if yr money grows on trees send me some cuz i dont have much just 1k.
get yrself a psu and case. idk much about case and psu.
and if u dont like amd cpus , go for i5-2500k and a min msi gd-43(b3)(dont know exact model).
i recommend amd way coz it is cheaper in case yr budget overflows
