I recently built a brand new lynfield cpu 2.66 quad core w/4gigs of gskill ripjaws, gigbyte p55a-ud3 & it seems a bit sluggish when web browsing & instantly opening up progs. Where is the bottleneck is it in the hdd's? That is all I havent changed yet. I have two SATA hdds in RAID 0. Will that make the big difference? If so which drives will help me get what Im looking for?
