I like the newer one you might be considering using, I tested this on my crap 713Mhz PC and it runs just fine, its also nicer too look at, loads quickly, and it has personality (The animated header at the top is a Plus). Since I surf forums a lot and I can highly recommend with experience to use the new forum as your default, as the current one looks bland, ugly, and dead. Well, good luck on your forum, thats my suggestion.
