With this capture card your limiting factor is going to be playback speed. 
If your system can play mjpegs at whatever size you plan to capture in then
you'll be fine.  I use this card and recently switched out dual Celeron 500
box (which worked fine at decimation 2) for a single Duron 650 which also
seems fine at decimation 2.  It doesn't drop any frames but it's a bit
sluggish when doing more than one thing at a time.  Of course it only has
96MB of ram and is operating completely over NFS so those have some impact
as well.
