I use it for 6 months.
16GB of ram. I turned without prob ProTools sessions of 40 tracks with many VST (rmx Stylus, Trilian, VST East west .......)
It is 2010. It is an i7. (Quad-)
It is ergonomically superb. It is almost as powerful as my mac pro 2010.
Flaw it gets very hot and that's saying something.
I would do without this choice prob.
Perfect for a home studio.
