Streaming Laptop

I've been wanting to get a new laptop for streaming and recording gameplay of my league games. My current laptop runs at 1.5 Ghz and has some stock intel graphics. I'm looking to upgrade to 2.5 ghz, 8-12 GB of RAM and a 3GB Nvidia G970m for graphics.

Are the specs I'm looking for good enough or should I look for something with a bit more power? My preferred companies are: MSI, Asus ROG and Alienware.

Thank you for taking your time to read this, it means a lot.
