Note: I am not going to overclock anything,also i have no idea what power supply will be required for this build 650 watt 750-850 or lower,please suggest which one should i take...
And finally i had 1 motherboard on my mind ASrock z77 Extreme4 ,but i'm not sure about that ,because i have read recently that it has problems with my GPU detecting and running at GEN3 ,which i have no clue what is.
Budget for motherboard is under or around 200$
I am noob about such things so 1 more question-Does crossfire require 2 GPU or 1,if 1 i would like my motherboard with crossfire support,Thank u for your time.

In order to crossfire, you need 2 identical AMD GPUs. The nVidia version is called SLI.

Take a look at the ASRock extreme6. VERY good board

that is not true, for crossfirex you need cards within the same "range" like a 7950 xfired with a 7970. I had a HIS 6790 xfired with a Powercolor 6850 for a time and it worked great. sli requires cards being the same, such as gtx 660ti 2gb with another 660ti 2gb (I think they need to be the same speed too) but can be different brands.

The ASRock Z77 Extreme4 is pretty good and is very cheap where I am 🙂

If you want to have the option to Crossfire at a later time, you will eventually need a bigger PSU. 650 watts is great for one HD7950, but you really ought to at least have 750 watts for two.
