NEED HELP BUILDING. Help is appreciated :)

Hey sythe, I'm looking to get final feedback before I start my order for my new rig.

I'm looking to build a gaming/streaming/recording and video editing rig.

I just wanted to know some of your thoughts on some components.
I have about $1500-1700(incase i include capture card) after the case and OS.

Thinking between the i7 3770k and the i5 3570k:
- Don't know why I should choose either over the other
- Which one would be less affected by my recording? (FPS jump from recording to not)

Pretty set on a 2GB EVGA GTX 670 1080mhz Video card (probably will SLI later)

Thinking about a Plextor 128GB SSD; 1 TB WD Black HDD

Between 8GB and 16GB G-Skill memory:
- again, for the usage while editing and or capturing while playing the game at ultra settings.

Blu-Ray writer: Found a LG one for about $70, seems legit.

Between a 212 evo and noctua nh-d14 for heatsink

Asus p8z77 v-pro or p8z77 v-lk mobo:
Only perk I can see that is the difference the pro has is Wifi, and although it is definitely a plus, I can live without it- is there other important features or flaws each mobo has I should know about that people have experienced or heard of?

XFX750W Pro750W Power supply for sure

Help me please, I'm really excited and want to build this ASAP
