The PSP is designed to run at 333Mhz, so all you're doing is making the system run at the CPU stock speed.
They're underclocked by default to save battery power. Initially they were all locked at the lower speed, but after a while Sony let developers flick it up to the higher speed from within their code.
Makes sense to underclock by default, since watching a video, listening to MP3s, looking at pictures or using the web browser really doesn't need much power.
It can make games noticeably smoother running. That in turn can reduce the blur on PSP screens (especially the original models like mine). The faster speed allows more fps, which means less changes between frames, which means less obvious after image.
I don't think I've lowered the speed on my PSP since I first CFWed it way back in the v2 days. Makes little difference for new games but some of the old faves like Wipeout and GTA are better for it.
