I am ready to buy my parts to build my first PC. Just want to do one last check. I know the I5 system I have configured is better than the AMD system. My question is, is it worth the extra $155 for what I plan to use it for - which is mainly multiple browser web surfing and multiple Microsoft Excel files open at the same time. Basically web and productivity multi-tasking. No games or video editing. Here are the systems: Intel I5-7500 System https://pcpartpicker.com/list/H8d3BP AMD A10-7860k System https://pcpartpicker.com/list/b8TmKZ Also - when buying all the components, will all necessary cables come be included or is there anything else I need to buy for assembly?
