My specs are:
Cpu: i5 4690K at 4.5 GHz
Motherboard: Asus Z97-A
PSU: 650 watt
Ram: x2 8Gb DDR3 1600MHz
Currently I have an Sapphire RX 480 4gb nitro+
The ideal purchase for a new graphics card would be an RX Vega 64 of some kind since I like AMD and I have a freesync monitor. I'm wondering if my 650 Watt Power supply is enough or if any other components need an upgrade. I have heard that GPU prices are going down by about 20% this month, is it worth waiting for that and should I keep waiting to buy anything until the next gpu lineup from amd comes?
