Since the video card in my old Toshiba Qosmio X775 fried, I needed something to play the games on. I decided then to build my own desktop gaming machine.
Since it was my first time, everything went pretty slow for me: I had trouble installing CPU cooler, etc, etc. Also, wiring could've been better. But then I've finally built it. All games run very fast.
I'm delighted about my own build.
