I'm very happy with my i7-4770K. Between that and the SSD, where it used to take me 4-1/2 minutes to boot to Windows from a cold start, it now takes less than a minute. Of course, other programs will be different. And that's with no overclocking of the RAM, CPU, or video card.
I usually shop at Newegg but for this build I did some extra shopping around. I have a MicroCenter store not too far from me but they also have a website. Where newegg wanted $339 for the CPU I got it at MicroCenter for $250. Newegg wanted $189 for the mobo, MCenter had a combo deal where the mobo was $150 when I got the CPU. So I saved $128 just on those two. And I have rebates coming on 4 or 5 items, I can't even keep track of them all, I'd have to check my emails, but they're all between $15 and $20 each.
My point is if you shop around you can save enough on some of this stuff to upgrade other things. Like I said, the SSD is your best investment right now and the prices are dropping a lot.

added: did a search on the H81M mobo. That's an MSI brand, not Asus, and
the prices I saw on newegg . . . . . . . I wouldn't even consider them.
