They said they purchased it in 2004, and it was given to me as a graduation present in 2011, so someone at our church must have upgraded it somewhere along the line. Doing a little searching, the Quad came out even later, in 2008 so it must have been around then. Presumably for the upgrade to Windows 7.

Now that I think about it, pastor's son was a gamer that spent all his time at the church, and I always thought it weird that a church had a discrete graphics card with DVI output in a back office machine...
