Well as I mentioned, try some of the things I pointed to in my previous post - you may be lucky. Unfortunately minimum required specs aren't very much to go by when it comes to games and there's nothing worse than buying a game and then not being able to run it. If you do decide you want a desktop system, you should consider building one yourself. You can build a much better quality system that is perfectly suited to your needs for far cheaper than you can purchase a pre-built system. Also, you're in the right place here - if you post your needs for your system with an approximation on your budget there are many members you will be more than happy to offer you advice. An adequate gaming system doesn't have to cost the world and even if you decide not to purchase it will still give you an idea on what you can get and how much it will cost you.
