I agree, 1000w is excessive. 700w or even 750w I'd say. And I also agree to nhasian, an SSD would be an add-on well worth it, but be sure to keep your seagate you have picked out to be a secondary.
Well I was planning on doing sli in the future and also adding an ssd and maybe another harddrive but I'm going over my budget already. Im basically future proofing my system
