what uses do u have for it, and do you see a noticeable difference? i'm getting a 2500k i5, since it is cheap @ 180$ or so, but do not know if it would help me to overclock (fairly new so do not want to fry my parts). i'd be just above average setting new gaming, intense tabbed browsing, watching vids and the general sort. not much photo editing, no video editing. heard that vga card is the bottleneck anyways, so what good is going for 2.8ghz to 4.5ghz?
