Yes you can, however, keep in mind that this faster speed is only valid while you are working on the VPS.
This means: When you download a big file via de browser on the VPS to the VPS harddrive, it wil go very fast (1000mbit with good vps)
However, when you then send the file from your VPS to your HomeComputer, you are limited by the home internet connection (eg 30mbit) and it will not go faster
So vps download will not speed up your home download. However if you want to upload & download files to websites without getting them at your home, vps will be much faster in this than your home.
