ive had decent luck by renicing the X server to a lower priority (higher number) and doing the opposite to jackd. depending on how your X is started (gdm, xdm, startx) the way to nice it on launch may differ, but give it a shot..

im not sure 'top' can be trusted. for ex running ices doing a realtime ogg encode takes 5-6% CPU , without X running, and as soon as X is launched, that number doubles, according to top..
