New builder attempting a Llano build, please advise...

Brand new to the forums, so please forgive me if I'm not asking correctly for adivce for this.
Just seeing if anyone has any recommendations or advice, or criticisms for this build.
I am a first time builder and will be using my two 500mb SATA II drives from my previous system, as I don't feel I need more than that, but didn't know if I should maybe pick up a SATA 6 drive for the speed. Also using my DVD/CD burner from the previous system.

Please let me know what you think, and thanks in advance!

Your better off just getting a Phenom 955 if your not planning on using onboard as the A8-3850 uses an Athlon II processor.

So I would be incorrect in thinking that adding the extra card would act in a Crossfire capacity in this build?

The main reason for that would be to help with the various graphic design tasks required by this computer.
