Just got given an i7, Mobo, GPU and some RAM...

[YungestBaloney]

A friend just gave me his old i7 with a load of parts, looking to build it up this weekend but unsure what parts to go for, in terms of what I'll be using it for - I'm a Graphic Designer using mostly Photoshop, Illustrator, Premiere Pro & After Effects - No real plans for gaming to be honest - Currently using a Macbook Pro i7 2.0ghz 2013 for work.

Here's a list of what I've been given:

• 
  Intel Core i7 920 (will overclock)
  ASUS Rampage II Extreme with SupremeFX Sound Card
  AMD ATI Radeon HD 5850 PowerColor 1gb
  Corsair Vengeance LP 16GB 1866mhz (4 x 4GB)
  Corsair H50 Quiet CPU Cooler

These are the parts I’ve been considering:

• 
  Case - Fractal Define S / NZXT s340
  PSU - PSU Calculator Says it should be around 400w, however my friend ran a 650w and recommended me to do the same) EVGA 600 W 80+ PC Power Supply Unit / Corsair VS500 / EVGA 650 W G2 GOLD
  SSD/HDD - Samsung 850 EVO 250 GB
  Fans - Corsair AF120 Quiet Edition 120mm x2

Are there parts you could recommend? Reckon it's worth changing the GPU? Looking to keep it cheap but if it's worth spending the extra money I can stretch my budget a little.

Honestly, that i7-920 is a bit old. Sure it has juice, but still, it's a bit old, maybe can't suit your needs the way you want it to, especially in Photoshop 2017.

don't consider AF120 QE 120mm fans. they used to be alright but can't compete with the only marginally more expensive better competition (Cougar, Noctua, BeQuiet)

except for the EVGA G2 those are all low quality supplies.
an EVGA G2 / G3 / GS, XFX TS, Corsair RMx, any Seasonic or Super Flower should do fine.
