My total budget was around ~400euro so don't expect much, but it's a damn sweet upgrade from my Q6600 PC+HDD+DDR2(lame frequency - tiple channel fml) from 10 years ago.
Case: Aerocool Cruisestar (Am I a douchebag for liking it too much?)
Mobo: Asus H110M-K
PSU: 600W XFX P1-500B-XTFR
CPU: i5 6400 (might sell it in a couple of months and go for an i5 6600K)
GPU: The one I already have - Nvidia 650Ti
RAM: HyperX Fury 8GB DDR4-2133MHz (HX421C14FB2/8) (might go for 24GB or 32GB max soon - it's very cheap plus CAS Latency: 14)
SSD: Samsung 850 Pro 128GB (combo with my old 300GB HDD)
ya for 400 its not bad. Keep in mind Ram after 16GB is pretty redundant right now,
Stick with just 2 8GB for now then upgrade later. unless you mean that 24GB in 1 stick, if thats the case then id say go for one of those.
