Or is it just because of OS compatibility?

You can use a modern GPU with DirectX without any problem if there are drivers available.
For example the last Ati 12.4
Windows XP support for the AMD Radeon HD 7900 Series, AMD Radeon HD 7800, and AMD Radeon HD 7700 Series

In addition to Windows 7 and Windows Vista support, Catalyst 12.4 now also introduces Windows XP (64-bit/32-bit) support for the AMD Radeon HD 7900, AMD Radeon HD 7800, and AMD Radeon HD 7700 Series

So to use a old Operating system != old Hardware.
