ok guys, i have finally decided loading times are too damn long, i am ready tho upgrade. My current system is the one in my sig. if i went with the 165 would i have to reformat? if i went for the raid 0 i would get two 160gb hard drives and put them in a raid 0. they would be the new sata 300mb/s or whatever they are. i would use my current harddrive ofr back up to that array. would i have to reformat if i went that route? which should i choose to give me overall better performance in loading?
