18k worth of laptop is not worth it unless it's a bargain sale. first to consider is the battery life since it has been used you dont wanna spend another 6k or more for battery replacement. also at that price i dont think it will perform better as laptop slows down faster in just a couple of months. it may either jeopardize the system's performance particularly the graphics especially if you're planning for cam2cam communication. i suggest you spend another 10k or more for a better performance laptop or better yet buy a new one that costs around 19k-24k
