I'm guessing you're using the i7 720QM processor, which was released in Fall of 2009. Given that it's now an 8 year old processor, and you're only running 4GB RAM, you're barely going to scrape by - not just because of the age of the processor, but all the data pipeline and memory speed that goes along with that age of a computer.
Yes, it will run, but it won't be excellent performance.
