This is my first build I was wondering do you need the cpu (ddr3) to be the same as the gpu (ddr5)
My specs:
Cpu: i5 4690k ddr3
Gpu: msi Gtx 960 4gb ddr5
Motherboard: z97 PC mate
Make sure you have a good power supply. I suggest looking at this list and gettting something at least from the Tier 2. my Favorites are the Seasonic s12G and the Rosewill Capstone.
