So, what do you think, will the difference in sound quality be noticeable if I upgrade from Behringer Guitar Link to Apogee's Jam?

The Guitar Link is pretty noisy.

I'm a OSX user and I have to money so...
Yes. Apogee will have a far higher quality DI input and converters, not to mention, better drivers, support and (more than likely) less latency.

maybe you're not saying the right things? an amp likes to know you care.

Not kidding. Just wishing it will be clearly noticeable and worth the money. I mean like a huge difference! Already ordered the Apogee Jam 96k. Can't wait it to be here. Thanks!
