So I have a main gaming rig thats been doing double duty as my VR PC. I have been hunting for a good deal to get me started on a dedicated VR machine as my PC gaming and VR spaces are in differecnt locations of my house. Well I think I found it. I got a used Ryzen 1600 with a AB350 Pro4 board for $90. This plus RAM, case, cheap SSD and I am just under $300. I already have a extra monitor, wifi card, keyboard, mouse and power supply.
Question is do I go for a used RX 580, Fury or Vega 56 for it? I am using a 1st gen HTC Vive now. We play a mix of VR games in the house but none seem like they would be too demanding. With VR is the 4GB of VRAM on a Fury going to limit the PC? Is a used Vega 56 for abount $225 worth it in a post RX 5700 2019? Sould I get the 580 and just expect to upgrade when I get a new HMD?
