Not wanting to settle on less than the monitor's native 1680x1050 resolution,
I waded through a great many video cards at Staples, eBay & MicroCenter and
ordered an AMD Radeon R5 230, which has a semi-favorable free vs. proprietary
drivers discussion here:

All the Intel chipsets seem to come with attached computer motherboards, and
I don't want to end up with the proverbial farmer's axe (in the family for
generations, with numerous replacement handles and heads).
I'll post my progress after the order arrives.
