Just picked up an AMD R7 250 for 12 EUR from my local classifieds, and I temporarily put it into this system for testing purposes. This is mostly for the sake of curiosity, as I wanted to see how AMD cards compare to their Nvidia counterparts in terms of supported features. This particular card has VGA, DVI-D and HDMI connections. During my tests, I was deliberately using HDMI, but I ran into a few issues with that. At first, the card wouldn't display anything over HDMI, just giving a black screen, while VGA and DVI worked fine. I thought the port might be dead, but nope, turns out I just needed to use an older HDMI 1.4 compliant cable. For some reason, this card doesn't like my newer HDMI 2.0 cable.
For the drivers, I'm using Catalyst 14.4 pack 2 which are still available from AMD's website. This pack seemed to install ok, but the main GPU driver was missing after the installation process was finished. I had to install that manually via Device Manager. Oddly enough, this initially detected the card as an "Radeon HD 8800M Series" but I manually changed that to "R7 200 Series". Not sure if there's any meaningful difference between the two. In any case, here's what GPU-Z says about this card:

Next up, I fired up the driver panel and wanted to check the image scaling options. And just as I had heard, these work correctly on AMD cards under WinXP, even when using a HDMI connection. This is in contrast to Nvidia cards, where this functionality either needs (much) older drivers or a plain DVI to DVI connection.

Then, I checked the black level settings, and was pleased to see that you can select between Full and Limited RGB straight from the driver panel:

This is another thing that Nvidia cards lack under WinXP, and you need to use third-party tools to toggle it. I haven't tested all the other driver options thoroughly at this time, but there's certainly some interesting stuff in there. This is my first AMD card (I have some ATi branded ones) so I wasn't sure what to expect.
P.S.
Table fog works on this card with Catalyst 14.4 drivers. However, due to the lack of 16-bit dithering, it has that ugly color banding in Thief 2, same as Nvidia cards. The difference being, on this card table fog works even under Win7, which isn't the case with my GTX 970 for example. One thing that kinda disappointed me was that Integer Scaling isn't available on the R7 250 under Win7. Apparently, that option needs GCN2 hardware.
