I bought one from Best Buy for $40, but I don't want to keep it for that price. Just wanted to see if it fixed the problem. I see quite a few on Ebay pretty cheap. What do I want to look for when purchasing one or should I just take a pick?
in sound quality, no. Computers process data, not audio information. I've learned a great deal from a Mr. Bob Katz about this very thing.
The main concern is just be able to handle whatever resolution you want to record in. For example, you can expect to play audio off an external firewire harddrive.
Maybe like 20-30 tracks of 24-bit 48khz files, sure no problem. But 100 plus tracks of 24-bit 192khz+ audio?! that's like "holy shit" in all capital letters.
So in that case, chipsets, ram, drive speeds, and capable data processing is important

.
I had some guy ask me the other day, "firewire is making my shit sound dull and all muffled. What gives, holy man?" and I replied, "dude, firewire can't make your shit sound dull...is the fact that you put a thick ass sock on all your mics that makes it sound dull". Plus considering he records in a garage with terrible acoustics and just all around poo poo gear. You get what you pay for.
Even if a bad as "mojo poo jave" 1600000 x 120 firewire PCI card was out there, it wouldn't even make a .000000001% difference in sound quality. So in our case, it should be free or worth .000000001% of a dollar.
I had talked about all that a long time ago on here. In digital, it's not really ram, harddrive speed, your chipset or your cpu power that make things sound "digital". It's things like poor A/D/A conversion and instable clocking that makes things sound "digital". Aside from the fact that digital is, well, "digital".
Things like cheeta drives (or giraffe drives...whatever they call em now) ,SCSI drives and all that bad ass data processing power come in handy for massive, high quality sessions.
