Those components are good and will game decently if you don't want to overclock your CPU or crossfire your graphics card. I personally don't have an overclockable CPU nor do I crossfire and I don't find problems running games on decent settings (on 1080p res.).
I would go for a B75 or H77 motherboard instead of that H61 as it is previous generation. You'll only spend $5-$10 or so more, anyway.
If you want to overclock, buy an i5 3570K with a Z77 motherboard. If you want to crossfire in the future consider a 700W PSU (that's 80+ certified, of course).
In summary, your PC build is great with the motherboard as an exception. You'd play most games on high on 1080p at 50+ FPS.
