Help Needed! Is either a good system??

Hi, I'm new here but starting a long search for a good all around desktop, and I don't know too much about them. I'm a physician who needs to access imaging results (MRI's, CT's, etc) on a regular basis, as well as word processing etc. In addition, my wife is an interior decorator who uses graphics-heavy programs to recreate rooms of a house and manipulate decor; I also have two kids who enjoy games and haven't been able to play some of the modern games because our computer is too "old" (two years). Having said all this, I have two quotes for desktops and I'm wondering if osmeone can tell me if they are good systems, and would be able to handle the tasks I've described? Thanks in advance to anyone who can help, I like to refer to the experts on things like this rather than wing it! Below are the two sets of specs sent to me:

Absolutely, any chance you could offer some guidance on what to get? I know basics about processors, ram, etc, but not much about the current technology.

My understanding is they are not pre-built per se, as in they are not built yet but can be built quickly if I want one. They are very similar to others the store sells that are pre-built though.

Hi guys, I actually live in Canada, not the U.S. As for budget, $800-1000 if it'll get us a system that we can get 3-4 years out of while still being relevant. As for the components I need, this is where my lack of expertise comes in. I guess if you could suggest a processor, ram, video card, sound card, etc., I could go from there. I don't really know what else I would need!
