PC Build Compatibility



Thanks, but since I'm a little constricted for time, and can't wait for returning and reordering, is the GS power supply really Nessecary or can I leave it as is
 


Its recommended not needed 100%
 

No argument to the thermal paste, but is it really Nessecary to switch mobos since I've based lots of my components around it, and I'm a bit time constricted.
 

Ok, but do you have any suggestions? I was looking at the GIGABYTE G1 Gaming GA-Z97X-Gaming 7 LGA 1150 Intel Z97 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard, but is there anything else you suggest?
