ouch, that really sucks rigs. I had the ring of death as well, but at least Micro stepped up and fixed it for free. I noticed your demo....but figured I would start a new one for the release. Haven't heard any problems with pc, hope it gets fixed.
Any other games you are looking forward too?
Halo3, Mass Effect, Mario Galaxy, Super Smash Brothers, Call of Duty 4, Progect Gothom Racing 4, and .....hmmm some motorcross/supercross/off raod one, can't think of the name atm.. I'm sure there are more, just can't think of them all!
