Hi!
I’m building a new desktop with a budget of $2000 (give or take 200)
I have an idea on what I’d like for the most part, but no clue about some other parts, especially struggling with choosing of brands/models.
Some information to help you help me. 
Building in Canada. Meant to be used for 1. Rendering 2. Mild Gaming.
I primarily work with Photoshop, Indesign, Illustrator, Autocad, Revit, Rhino, Sketchup. I’m aiming to learn&use 3dsMax as well in the future. I use VRay as my render engine, and learning a bit of artlantis for fun.
What I have in mind:
Processor: I7-4790k
Motherboard: ASUS Z97-Pro (WifiAC)
Graphics Card: GTX780 3GB, eventual upgrade to a second. Which manufacturer?
RAM: 2x8GB, eventual upgrade to 32GB. Brand? #mhz?
HDD: 2TB. Thinking WD but open to suggestions.
SSD: Samsung 840 Evo 250GB
PSU: Guessing I’ll need around 750W?
Cooler: No Clue. I would like to OC though.
Case: Absolutely Clueless.
OS: Windows7. No need to purchase.
I’d appreciate all advice&suggestions.
