Have you considered having eCollegePC build you one? They will build one to your specifications and provide a 3 year parts and labor warranty at no extra charge. Shipping is free too. A bunch of people here at GB have gotten new gaming computers from them. They are also very fast in building one for you.
This is an example of one that cuts no corners for $1053, free shipping and 3 year warranty. You can always back off on a couple of things to stay under $1,000.

You can always add more RAM later if you need to, but if possible, I'd go with 8 GB.
If hubby knows what to get, check them out. EcollegePC
EDIT: I should add that unless they have changed, places like Best Buy sell computers with integrated graphics and as a gamer - even the new adventure games - you will not be happy with one from there.
