Hi Robert,
I didn't try that particular one, not positive about the soundfont side of things.
You may want to check if you're considering purchasing one.
I have an Audigy 2 NX usb I used to use with the old laptop. It worked well.
I think my old laptop was faster somehow. I used to only have about 2ms latency when using Forte & Asio4all with it , and I had no noticeable latency when using the Audigy 2 nx & soundfonts. It had 3.06 ghtz though which I think was pretty powerful for a laptop..
