I built my current PC using one of those PCPartPicker guides, and I’m very happy with it.
The only issue I had was the video driver. I use the Linux Mint Long Term Support version, and the kernel didn’t have a recent enough driver for my card. I just needed to switch to the latest kernel and it was good to go. I actually had no idea how to troubleshoot it, and went to the LM forum to ask for help. I was reading through the guide on what info to supply with help requests and realised that the example fault and solution were the exact ones I was facing!
I agree with the reporter - he needs to port Doom to that mofo.
