You are building a computer with the most current CPU and motherboard. Why would you add a 2nd generation SSD. IMO go with any of the current 3rd generations, Intel, Crucial, OCZ, Corsair. There's an improvement of from 3 to 6 gbs. You won't be disappointed in any.
There are some very good articles here at Toms. Read'em all. I noticed you didn't mention a HDD storage drive. I hope you plan on having one because that helps to preserves your SSD's performance and longevity. Good Luck man. Keep us posted.
