Now I just ordered an gtx 970 and got this game with it, I have never used gog.com before. Just a little confused on how to download the game properly. The game is broken down into 4 gig parts. Am I supposed to make a Witcher 3 folder and plop all them in there and then use the installer when they're all in the folder? Just a weird download process, never seen anything like that

I think most people use the gog downloader.

You can also try their client, gog-galaxy, but it is in beta and sometimes has problems.

Oh okay thank you. Another question, not exactly sure how to use it. how to I download the game in it ahah

figured it out, nvm thank you

I would avoid galaxy considering all the problems people are having and it is still beta. Also on galaxy the files won't download at the full speed of your connection. Use the downloader instead.
