i checked out 7rc to see what difference it had with my everquest game with 2 to 3 toons compared to vista 32 bit i have. if it did well, and it did, i was wanting to try vista 64 bit for 10 bucks from ms hoping it would do well. i havent used it much in the game yet. running around with a single toon seemed to be better than the 32 bit. as for your question, i would wait awhile so all the bugs can be worked out first. had some minor stuff come up with 7rc but i think it will be a good os in the future esp with online gaming.
