I have had Dell business class computer before. When I ran a business. They were the best of the best for the purpose for which they were intended. This one is no exception. It is fast, stable and runs any program I have need of with ease. It starts in seconds not minutes, any program you need is ready when you hit start. Thanks the seller for such a great product at such a great price. It arrived a day earlier than expected. Bravo to the seller.
