You'll only notice a speed increase with applications that need to caculate very large numbers, like encryption keys and certain scientific apps. Everything else will basically run just as fast in 32-bit mode as it will in 64-bit. There are exceptions in certain media encoders that don't have hardware optimizations for 64-bit, that may actually run faster as 32-bit apps. Anyway, I think this article summed it up pretty well: http://lwn.net/Articles/199229/ -Richard -- gentoo-user@gentoo.org mailing list
