It is a good computer for someone like me, who has only really experienced pc gaming on a shitty laptop. The only problems I have with it, are the alienware UI, which is just terrible, and the hard drive, which I am going to replace, then I will uninstall the alienware UI.
I will also be looking into a new controller, hopefully the steam one that is coming out, because I have got used to PS4 and X1 controllers, the 360 feels like a step back.
Games wise, you are not going to get massive frame rates on new titles, but you can see the difference compared to PS4 and X1 titles. I was happy with how resident evil remaster and ground zeroes looked and played.
Having purchased this, I would be more open to buying a more powerful PC, and gaming on that, instead of getting a console.
