[mythtv-users] DVB-S: Hauppauge nexus-s versus Twinhan/Skystar cards

I am looking at replacing my external DVB-S/FTA receiver with a dvb-s card
in my myth box.
As there is roughly US$100 difference in cost between the high-end Nexus-s
with hardware mpg2, and the low-end Twinhan/Skystar cards, I would like to
know what the CPU load difference is between the 2 types.
I understand that the low-end cards will have to split PID on the
transponder in software, but considering the stream is already mgp2, I
wonder how much work/cpu-load this really is. Does anyone have any
comparisons for these two type on roughly equivalent hardware?
I am running myth on an AMD64/2800+, which during all my myth-usage stays in
the lowest cpu speed of 1GHZ; recording with PVR-150 uses about 2-3% cpu,
playback on FX5200 card uses roughly 18% cpu; this makes for a reasonably
quiet system, and I'd like to keep it that way. (I do transcoding and
compiling 'after hours' and then it runs at full speed and 'full noise'
Any information would be appreciated.
