essency, i would think the type of your sound card does indeed matter.. an onboard card simply doesn''t have the power input or output that an after-market card will have. i am using a soundblaster Audigy series.. in addition to having a whole lot of punch, and dolby decoding, it has a face plate which goes into your drive bay. this plate has RCA analog, fiber optic, and SPDIF inputs on it with volume control (as well as 1/4" headphone jack, a 1/4 mic out, a firewire port, full size midi ports, and a remote control

). i run RCA cable red and white from the turn table and plug it directly into that face plate. then i just cue the record and hit record... this way i don''t need an external box (though they exist, for laptop users). this card alone is what makes my computer my complete entertainment center, aside from a real tool. crisp surround sound.
the quality/peak on this is very good. i was managing a band for a while and actually made a recording of a solo acoustic run, with vocals, on the same sound card setup, on my buddy''s computer .. in his LIVING ROOM, on his PC, we recorded the acoustic guitar directly into the machine then recorded the vocals. mixed it in Reason, and burned it to a CD. it took some testing to find a good balance between the low and highs on his vocals, we had a couple peaks, but we mixed them down. from the CD you''ve got a professional recording. you can''t tell it wasn''t done in a studio.
the audigy series starts pretty cheap, suprisingly. best deals on pricewatch but Best Buy has them for a good price. you can get the low ends or get the ''professional'' unit which has the face plate and a remote. i personally think it''s a must for anyone who wants serious sound comming out of their machine. you''ve never played Unreal until someone frags you from behind and you jump like there is a dump truck comming through your wall.
i havn''t seen other brand''s of a similar set up, though i''m sure there are a couple other ones. Roland makes a similar card but it is much more powerful, and it is much more expensive.. it is used for inputting from a mixer pannel, something up to 10 different devices. its crazy.
