I've run it and it was like treacle on my PC especially the 2 CPU tests which run at only around 0.3 FPS !
I will test it out when I upgrade to a 64 bit PC (hopefully) later on this year.
I downloaded it within an hour of release when the servers were taking a hammering, and it took me nearly 8 hours as I was only downloading at around 20Kb/sec (around 3 times dial-up speed) even though I have a 1mb broadband connection.
My Radeon X800 Pro really took a hammering but at least I can say that I've seen it apart from the 'Deep Freeze' test.
Finally it also requires a graphics card with at least 256Mb video RAM which my card, thankfully, has.
