honestly... spend the extra 40$ and get a really cheap video card and a mobo without a built in gpu...
EDIT: I looked it up, it costs an extra 25$ only!
Nothing is playable on the build in gpus anyways, and even if you plan to do absolutely no gaming you still have driver support issues... With an external card those just go away.
I would recommend an nvidia card since they driver support is better.
Video cards:

8400 (50$ including shipping) =

Those will give you much better performance and the peace of mind of an easy install and lots of driver support for years to come.
On an "office" computer I would put the above mentioned 7200 card with a cheap motherboard from asus. For the mobo also get the latest chipset you can... this again is good for ensuring the useability in years to come...
Asus just makes reliable good boards... with an ECS you can expect 10 hours of fiddling, replacing parts, and making every incompatible thing work... with an asus nforce mobo it just works as soon as the parts are in.

however, the cheapest 690G motherboard costs 72$ shipped (at least at newegg)... saving those 25$ is just not worth it... you will spend many many hours messing with it getting it to work right... while the motherboard and gpu i suggested will only require you to plug them in, and install the latest driver from nvidia for whatever it is you could want.
benefits of mobo + gpu for extra 25$:
1. Plentiful drivers for everything, which are up to date and continue to be updated.
2. Quality products that will last long.
3. Much higher video performance and quality, as well as more varied plugs (DVI + VGA, vs VGA only on a built in board).
4. Save hours of labor trying to get things to work right.
5. More...
