The first thing I notice is leadtek on the video card. I would go with evga if the option is available.
Not really understanding the dual raptors, why not have a strictly storage hd as secondary?
Personal opinion is unless you have a lot of money, why go with fx-55? It's pretty clear that in the near future multi threaded software will rule the cou(sp?). Sure FX is at the top right now but they have mutli proces supporting software coming out as soon as early october(FEAR). Plus it multi tasks like lightning and still outdo most singlecored processers on single threaded tasks.
