First time new build, mass RAM confussion

[ChienLunatic]

Greetings
I will soon be starting my first build

ASUS Z97PRO wifi
Intel Core i7 4790S
Fractal Define R5
Seasonics platinum 400W
Windows 8.1

I will no be doing much gaming but will be doing photography work, large RAW files and occasionally my wife might need it for HD video editing.
I am totally confused by what RAM I need to get and how much? Thought of starting with 8gb and adding more if needed.
Many thanks for any advice.

Any DDR3 RAM will do, preferably 1866Mhz or higher.

imho you should start w/ 16GB already (2x8GB). Its time for 16GB for power users (photography work, large RAW files, HD video editing etc).

Something like that:

PCPartPicker part list / Price breakdown by merchant

Memory: G.Skill Ares Series 16GB (2 x 8GB) DDR3-2133 Memory ($125.98 @ Newegg)
Total: $125.98
Prices include shipping, taxes, and discounts when available

And in a no related issue, look for a stronger PSU for your gaming (550W-650W). You will need that extra power for a good gpu. Seasonics is the perfect brand though.

I like where you were going with this but I would opted for these http://pcpartpicker.com/part/gskill-memory-f32133c9d16gxh G.skill 2133Mhz 2x8GB CAS 9 for $150. The speed with low CAS will go well with your build.

No guarantee the 4790s will be capable of running 2133,so unless it's a good deal would stick with 1866 - if a good deal and can't run 2133 can drop them to 1866
