Help finding an old 478 P4

HI, my flat mate wants me to upgrade his computer and has put me on a very tight budget of £80.
His current setup is 1.9Ghz P4 478 with 400Mhz FSB
Some old board - not sure what company, no markings anyway
1x 512mb DDR400 , 1x 256mb DDR400
9800pro 128mb Sapphire with zalman cooler
80GB maxtor hdd
350W casecom PSU.

He just put the 9800pro in as a replacement for his nvidia mx 2.
From what i can see his computer is getting bottlenecked by the cpu and the 400FSB. (if im wrong someone please tell me)
so my question goes out that does anyone know if you can get a 3.0Ghz or more p4 478 that is built for 400FSB? as i don't want to be spending on getting one thats designed for a 800FSB and it not running any faster than the current 1.9Ghz.
And does anyone know where i would be able to get my hands on one - except ebay. (i cant get to the for sale part of the forum)
Or would it be smarter to pay out and get a 939 board and cpu instead? only they are both fading out now.
thanks

thanks, so you think its worth getting a 2nd hand 478 board or going for a 939? baring in mind it has to be agp, and im going to have to get a new cpu aswell, budget low.
