Need help with RAM upgrade

[Thomas_115]

I recently made a gaming PC and the specs are below
Corei7 processor
Sabertooth Motherboard
AUSU STRIX R9390 (8gb 512bit)

I spend all my budget in it so I bought standard Kingston ddr-3 8gb ram. Now should I buy another 8gb DDR3 standard Ram or go for a gaming Ram. Also what's the difference in standard and gaming ram like Hyper X Fury.
What should I do?

Thanks. I think R9 390 is good enough to get me 60 FPS. I would upgrade the system with 8 GB Standard RAM.
