I don't know about that card and it's not listed on h-node. Maybe someone
else can jump in.
With regards to games, have you tried similar free games? I don't know what
kinds of games you play. If you play FPSes, some gems are Xonotic, OpenArena,
AssaultCube, and Tremulous. If you play RTSes, there's Glest, Warzone 2100,
and 0 A.D.; I'm not familiar with 0 A.D., but I know that the others are
really great. If it's 4X games, there's FreeCiv and FreeCol. If it's
Minecraft, Minetest is pretty good; my brother said that it's not as good as
Minecraft, but a good clone, better than he expected. If it's MMORPGs,
there's Ryzom.
There are several other interesting free games out there, including Teeworlds
(an online 2D shooter) and OpenClonk (a platformer with fighting and RTS
elements, has online support).
