Personally, I think its silly to even consider going with the Quadro FX for gaming when you look at the dollars involved. Another thing to consider is what games you are talking about. The Quake engine is optimized for nVidia GPU's while the Havok engine (think Half-Life 2) runs better on ATI GPU's. Check out the benchmarks for the games that you intend to play most often before deciding what graphics card is right for you.
