The Kickstarter for Star Citizen has some updated answers to frequently asked questions about Cloud Imperium's upcoming space simulation (thanks nin). The Star Citizen FAQ on the Roberts Space Industries Website has also been updated with these new FAQs, which cover things like their gameplay, their business model, and more. Here's word on system requirements:

There will be a lot of optimization in the next 24-months, plus the usual fast pace of technology, so it is hard to say absolutely. At the moment you will be able to play it on a dual core PC with a GTX 460 or greater and 4GB of system memory. If you’re running an i7 2500, 2600, 2700 or better with a GTX 670 or greater then the stars are the limit! Since the game is built on CryEngine, their system requirements will stay roughly the same as ours.
