Because the primary limitation of PS performance right now is memory. 32bit PS with a full 64 bit OS allows 4GB to be dedicated to PS rather than the roughly 3GB that you can currently max out at with PS on a 10.5 machine. Truly 64 bit PS would allow you to run a 32GB setup with 28-30GB dedicated to PS and absolutely no need to hit swap for most uses. Windows users are already in that position with Vista x64 and CS4, but CS5 will be the first Mac version with full 64bit support. PS getting better multi-core support would reduce the other major bottleneck. Right now PS doesn't handle more than 2 cores very well. -- M.
