Which distro should I use for such a computer?

Hello, I have a Samsung R580 notebook. I want to use it as a hobby so it doesn't just sit around. I normally know how to use Linux, but I'm not sure what to install on such an old device.

It has an i7 740QM processor (sometimes overheats despite cleaning), 8GB RAM, and an ATI Mobility 5470 GPU. I'm used to Debian/Ubuntu-based distros.

What are your recommendations?
