800-900€ PC build opinions

Hello, I live in Italy and this would be my first build (right now my PC is a Pentium 4!!!).

I'd mostly use this PC to game (1080p), media and maybe some rendering. My favourite retailer is Amazon, but I might buy some parts from a cheaper (yet reliable) retailer.

The build is:

CPU: i5 4690k (220€)
Mobo: Asus z97-a (with usb 3.1) (150€)
PSU: Corsair vs650 (65€)
Case: Corsair 200r (65€)
SSD: Samsung 850 evo 120gb (75€)
GPU: R9 380 4GB (210€)
RAM: already have 2x4GB
HHD: already have 1TB

I already have most peripherals (i might buy a good 1080p monitor later).
I'll probably overclock.
I also have a good sound card that i'd like to use!
Five years from now i might buy a new PSU and another GPU (for crossfire) if performance become an issue.

What's you opinion about this build? Should I buy the R9 380x or instead? Can I overclock easily with this mobo? any suggestion regarding the cooler (no water cooling)?

Thank you all for your help :)

Personally, I'd rather go with a locked i5 and a 390, but if you're really after that overclocking a 380/380X (when it comes out and if it's in budget) would be fine.

If you're into rendering, you might want to take a look at the 1231v3. It's essentially a 4790 without the iGPU, which if you have a dedicated GPU, you won't need.

Well you could start here potentially, built on the Italian part picker, a 390 costs a good deal more

You're probably right.
What's better: locked i5 + 390 or 1231v3 + 380/380X ?

I know that the first one is better for gaming, but the second one is a more "useful" PC and if gaming becomes an issue I can still crossfire!

It's pretty subjective, depends how much you game. I can't really look at prices because Italian partpicker is really patchy when it comes to what parts there actually are.

for buying components in EU, I mostly use mindfactory.de Cheap and fast delivery. You just need to know german
