How do you record D.I guitar??

my new motherboard line in is actually providing better output??

HIGHLY doubt that. It may sound the same to you, but judging from your threads and posts I'm going to go way out on a limb and guess you haven't been doing this long enough to make that judgement. Case in point, you made that judgement. Not trying to be a dick, just pointing out that better trained ears would know better. I mean you make a thread asking how to record DI guitar and then say your built-in soundcard sounds better than a dedicated audio recording interface, there is something really wrong there.

The Countryman Type85 DI is like the de facto standard in the industry. They are like $100 used look on eBay.
