Do it - you will be impressed. I recently rebuilt my home gaming system and went directly with Win 7 7077 and will go to the RC this weekend. I have had 3 blue screens - all of them caused by me mucking around with drivers. You may have to do some searching for drivers - you can typically default to the Vista drivers if need be. I am hoping they added more native drivers to the RC. nVidia just released new Win7 drivers yesterday.
