A December release window has been announced for Telltale's upcoming Game of Thrones series - time to make sure your PC's ready!

The minimum requirements have been listed on its Steam page:

OS: Windows XP Service Pack 3
Processor: Core 2 Duo 2GHz or equivalent
Memory: 3 GB RAM
Graphics: ATI or NVIDIA card w/512 MB RAM
DirectX: Version 9.0
Hard Drive: 3 GB available space
Sound Card: Direct X 9.0c sound device
Additional Notes: Not Recommended for Intel integrated graphics

Though these requirements look fairly forgiving, keep in mind that the recommended specs - which are likely to be a fair bit more demanding - have not yet been released.
