Hello, that's a broad question. The price varies from provider to provider. I would recommend two things; first take the time to look over some Dedicated Hosting Offers here on ForumWeb. You can view all offers from various companies here. My second recommendation would be is possibly Requesting A Host. You can make a thread requesting your requirements and providers will reach out to you and respond accordingly with offers. This will help facilitate the need of searching through various offer threads to only hear the deal is no longer available. You might get some good offers coming your way from providers in France regarding GPU servers. You can make a formal request here.
Good luck on your search and welcome to the forums!
