The Xbox 360 supposedly has a very advanced graphics card in it despite its relatively low price. Is it possible to remove it from the Xbox and put it in a PC?!
The main stumbling block, I would imagine, would be the necessary driver software, but surely unofficial programming could be done. I doubt anyone has actually done this successfully, but the possibility should be there.
