No... you won't see a huge difference, and hard drives don't require much power and SSDs don't use any power at all. Only your CPU and GPU requires power. What you want instead is a good reliable psu that can handle good loads power demands so when say you are folding, gaming, or benchmarking your computer won't fry and die on you. PSU is important, but the system you listed even with SLI GTX 580 won't require a Gold rating. Its nice to have but not 100% necessary. As others have said get a good reliable psu from $100-150 is all you need. Remember your computer will probably never get to 100% load even if its on 24/7 unless you 'want' to push it manually ex. gaming or folding or benchmarking.
Like for me my computer is on like 15 hrs a day and it never gets to over 20% load unless I choose to game. My system when at 100% load is like <500 watts. So a psu of 620 watts for me is enough as my psu is a proven stable psu that gives continuous power even at high load demands. Hope this has clear up some for you
Something like this psu is good enough. Silver Certified and have all the connectors you need. With rebates its only $120. The 12V rail is rated at 744 watts!!!
