It's an off-the-shelf generic laptop (Acer) with an i5 processor, 8 GB RAM and a 1TB conventional drive. I bought it to do my day job on the road, not with the intention of using it for audio purposes. An SSD-equipped computer would be much faster. Having more RAM would probably help, too.
Last year I also picked up a generic Acer with a Core i5, and a 5400rpm HDD, to use for a portable office, not music. The price was right.
I finally decided to give it a go with Sonar, just to be able to play with it when away from home. So I loaded ASIO4ALL, Sonar Platinum, and a few soft synths. Then plugged in some Sennheiser headphones, and my Xkey 25. CPU usage was low, and was pleasantly surprised by how well the Realtek sounded And with low latency as well, the soft synths were very responsive!!!
Like you said, it would be nice to have more RAM, and an SSD. My desktop PC has me spoiled. So I found a YouTube video on performing the upgrade. Here's a tip: if you think you may ever want to swap drives, or RAM, get a laptop with access from the bottom panel, LOL!
Hope your model doesn't have that issue! On mine the solution is to pull the keyboard, then unscrew and disconnect the motherboard, then pull the MB. The RAM and disk is located UNDER the motherboard, with no access from the bottom side. So this basically needs to be completely disassembled to perform an upgrade. Yikes! I've not yet been that motivated to risk tearing it apart. Runs fine once it boots up, and things that I need are loaded from HDD
Good luck with that new stage rig!!!
