Why else you go with a i3-3225 ? The 5 in the end is for the intel hd 4000, the i3-3225 is known for a htpc cpu for it's on die gpu(intel 4000) and lower power consumption.
And for a i3(you can't overclock) you'll be better off with a h77 mobo, also if you don't need the intel hd 4000, just get the i3-3220, same performance(only the on die gpu is different, it has the intel hd 2500).
That said, i don't know what's your needs.
