I was thinking of getting the RX 480 4 GB when it comes out when I have enough money on October. I have waited almost 2 months and still no 4GB variant yet so I'm look towards the GTX 1060 3GB which is priced the same as the RX 480 4GB. However, I have my doubts for the amount of VRAM the 1060 has as I'm a complete noob at PC hardware. Is 1 GB of VRAM a big difference and will 3 GB of VRAM be sufficient for most games?
