I think I could afford a new PC by now with all the money I spent for XWing...
A new PC isn't all that much these days depending on what you think you've got to have on it. Of course if you want to you can spend a whole lot more although you may be spending more than four times more for something that doesn't even double the performance in the area you are spending all that extra money on.
The question with any PC is what is it that you want to do with the PC. If all you do is surf the web or social media, a tablet is more than enough. If you want to play games at 60fps @ 4K that is a different story. There some in the early threads who have spent $2000+ on X-Wing. That is a lot of PC and a very good gaming rig if that is what you want to do.
Then of course, the way to your x-wing games might consume energy as well
