Please answer the question?

its a good cpu, but a little over kill for gaming. that card is a little weak for all the money you are spending. a raid 0 with 3 drives is a little more risk then reward. if i were you i would drop down the cpu, get 460 sli and get an ssd (faster and more secure then raid) over a raid 0. you can always add more hdd space as you need it.
