Depends on your personal use i guess. would it make any significant change from your current CPU use at max for your daily use? if so go for it. otherwise if you just wanna buy it because you wanna buy it.  that also is depended on you. a mini upgrade is always good.

realistically if it doesn't make sense in terms of what you get back from it.  i'd say it's better off saving the money & funding it for something really big next year or so.
