This will be my first PC build so i am not sure if everything is compatible with the motherboard. i am able to spend 2500$ tops so if there is something better please let me know. (i am not sure about the psu. if you can tell me how much i need that would be great. i am a gamer/video editor so i need the ram.)
and is the sound card worth the 170$
with the i7-2600k be woth it?

Many Thanks
