Nvidia is currently offering a limited time deal to encourage gamers into a purchase of one of the company's RTX 20-series graphics cards. The offer is valid for both desktop and laptop variants of the Turing-based GPUs, although to get all three games for free customers will have to choose one of the top-end RTX 2080 Ti or RTX 2080 models.
