Good wine to boost a PC a little old

I bought this card to boost my pc fixed that worked with an integrated graphics card.
Recognized without problems under Ubuntu 14.04. He just had to download the drivers offered by the system. On Windows, I had a little trouble finding the appropriate drivers for XP (my pc is dual boot). Indeed, those provided by the cd will not, the installation stops. I had to retrieve an older version (the oldest) on touslesdrivers and there, nickel operation. Even for old 3D games (type Return to Castle Wolfenstein, Medal of Honnor Allied landings, etc ...). This card needs space because its radiator is quite large (no heat sink is a passive cooling).
