That mobo doesn't even have a PCI Express 2.0 slot. Don't expect to run any newer graphics cards at full potential. Seriously, just stand up for yourself and tell them, rather then simply accepting every little thing they throw at you. Judging by the other stuff, I wouldn't be surprised if their expecting you to run off of onboard 6100, and really, what are you going to run on that? You just want to run Source smoothly, you say? My 6200 can barely handle L4D. If you're under a budget, tell us the budget, there are plenty of people here that will help you.
