with 320x240 (NTSC) on a dual 800 P3 (note: only one cpu can be used to 
encode) it usually gets about 50% (sometimes more sometimes less) usage on a 
single cpu. I can't capture full 640x480. 

Based on my estimates for getting full NTSC (400MHz *4) you would need at 
least a 1200MHz P3 (with VERY little margin for error)

(looking up benchmarks for mpeg4 encoding (using non-fast codec (aka 
divx4(win,linux))
