I am looking to build a new PC, reusing as much from my 7 year old build as possible. This is the list I came up with: https://pcpartpicker.com/list/pPC9FG. I am reusing my case, PSU, HDD and optical drive. It is mostly for 1080p gaming, but nothing too hardcore. Thoughts on the build? Is anything overkill or bottlenecking? Do I need a new PSU? It is more than 7 years old at this point.
