I've been running Ubuntu on an old HP xw4300 Workstation and while it's been great through the years, I feel that its time for an upgrade. I find that through my daily use of this computer I am constantly running into problems due to its lack of performance, so I have decided to build a higher end machine. One that if I feel like watching a 1080P video or all that way to playing a game on maxed out settings, it will run fine. I considered buying the Leopard Extreme from System76, however I found that I can build a better system more tailored to me for cheaper along with the additional feeling you get from building it yourself. I compiled a list of parts I chose to make this computer great but I am not sure how compatible they will all be on Ubuntu. So I would like to know if anyone has any feedback? Possible alternatives to better hardware? Anything would be interesting to hear.
