It will run on today's hardware, but like i've said, sh*tty, very sh*tty. Most people underestimate how demanding this engine is going to be. This is also why so many people are jumping ship on PC gaming and moving to the Xbox360 and Playstation 2. As I said in another thread, UT2007 is going to get most of its market from its Xbox360 version. Its going to be a reward to play it on the PC.
