Here is another for you to take a look at. I wanted to include a 1TB hard drive to prevent your friend from running out of space too quickly. It also includes a higher performing graphics card at the expense of a hyper-threaded processor. This processor is a very good dual-core that can be overclocked in the future for better performance. If you are willing to spend 50 euro more, you could get a GTX 960 which would be even better. The other build is good too I just wanted to provide you with some options.
