Here is what I have thrown together.
http://www.newegg.com/Product/Produc...82E16822135106 x2 for RAID 0 (throw your OS on here along with music, apps (such as office AIM, etc) and what not)
http://www.newegg.com/Product/Produc...82E16822136055 x2 for RAID 0 (throw your games only on this drive and loading times will be a breeze)
http://www.newegg.com/Product/Produc...82E16822136178 (you could use this solely for backup or split it in half and put a secondary OS on it)
http://www.newegg.com/Product/Produc...82E16814130072 (get one of these because you cant do SLi on x38 chipset or any Intel chipset)
