Please Help me with my system build

[Jayvi]

Hi everyone, Im new to the PC building thing.
These are the parts so far:

BitFenix Prodigy Mini-ITX Case
Thermaltake SMART 650W 80Plus Bronze PSU
Intel Core i5 3570K
ASRock Z77E-ITX Mini ITX Motherboard
G.Skill Ripjaws-X 8GB(2x 4GB)
Gigabyte GeForce GTX 680 OC 4GB Graphics Card
Samsung 840 Pro Series 256GB 2.5" SSD
Western Digital WD Blue WD10EZEX 3.5" 1TB HDD
Microsoft Windows 7 Home Premium SP1 OEM 64-Bit

Main uses will be gaming:
Skyrim graphically modded to the max and still playable
Rome Total War 2 (graphically modded in the future)
Movies

Will be connected to 40" LED TV
Now, I'm unsure of the motherboard, my selections are:
Asrock H77M-ITX Motherboard
ASRock Z77E-ITX Mini ITX Motherboard (most expensive)
ASUS P8H77-I Mini ITX Motherboard
Gigabyte GA-H77N-WIFI Motherboard
Which one do you guys recommend?

Also, is it worth getting the 3570k if I'm not going to overclock?
i dunno anything about overclocking and don't wanna stuff anything up by trying
And last question, is 650w psu enough for this build or should i go higher.

Thanks in advance for all the replies!

No there is no use for i5 3570k if you do not overclock it. I do not think overclocking of e CPU will be necessary with the CPU you are buying. ( If it is mainly for gaming and movie purposes)
You are overestimating the amount of power you need. 650w is more than enough no point in upgrading it. If you do not overclock your CPU I suggest,
Either:
Intel i5 3470
Amd FX 8350


There are both very good CPU's though the amd will provide you slightly lesser single threaded speed.
Regarding the motherboard, I would like to know the amount you are willing to spend
