Short and Simple, I ordered a custom built pc with a gigabyte gtx 1070 Ti 4gb, when i told one of my mates, they said 4gb doesn't exist. I checked everywhere and I can't seem to find one that's identical. I'm not sure of it but it seems to run perfectly on my pc. It has really confused me so I just need to know if this is actually real or fake? If needed, I can show specs (.txt or picture)
