In any case, minimum system requirements usually mean if you meet them, at best it will run slowly.
Some programs check hardware configuration during setup and will not permit installation if system requirements are not met. You simply get a message stating so. Some don't and just let you do the install anyway. Before you fork out any cash only to find it won't install, or it's a real slug, try the free demo first.
As a general rule, if you don't meet the minimum system requirements, it's best to just take a pass and perhaps find something else.
