For game dev you should always use a high end system because of the workflow.
No - not from my experiences.
If you develope a (casual) game on a highend machine you develope with specifications the lowend system can't support.
Many test cycles results in extra work on the performance.
Since we work with medspec laptops we save much time for performance optimization (thats our experiences).
Outside this Shadow969 will not buy a system for dev only but also for playing games so it's useless to discuss such a topic...
