New PC build for Windows 10

I am currently running an aging Windows 7 PC at home as my main computer, it still has some decent tin inside it unfortunately it's starting to flag alittle when I am doing Photoshop editting of my photography and the storage configured inside is outgrowing my needs as well.

When Windows 10 preview was released back in October 2014 I fell in love and started about reading up on what I needed to do to build a good PC that could take care of my techie needs and Photoshop requirements.

While reading up on how to spec a PC for Photoshop use I learnt the Photoshop uses the memory and then uses available HDD space when it runs out of memory. So I've tried to pick out good quality fast RAM (and will add more later).  later I will add an SSD that can be utilised exclusively to enhance Photoshop's performance (more info on that here  https://helpx.adobe.com/photoshop/using/memory-performance.html#assigning_scratch_disks)

I've got the following kit:

Motherboard: Asus Z97-K Socket 1150 VGA DVI HDMI 7.1 Channel HD Audio ATX Motherboard
Network adapter: Asus PCE-N15 adapter
