I've been thinking about building a pc for a while, I need something that will be powerful enough for video editing and gaming. I've researched and looked around on the internet for different components. I've attached a .PDF file with a table with all the components on, I was wondering if I could get some advice on what I've chosen if e.g. if there's better components. At the moment its around £700 which i higher than my budget of £500 - £600.
