The gamer Inflatable on the Halflife 2 forum has sended an email to Gabe Newell from Valve, because he was worried about the GeForce FX cards performance in DirectX 9 games. This information is NOT official, so it is possible that it is not correct.
Is a ATi 9800pro card really alot better for HL2 then Nvidia's FX5900? Or is
the difference not that big (quality & fps wise)?
I used to go for Asus cards all the time because I really like their in-game
OSD.. And Asus only makes Nvidia cards, so I was going to get a V9950 FX5900 especially for HL2, but if you say that's a mistake I will go for ATi this time.. Hope you find the time to answer my question..
The answer from Gabe Newell:
I have been a long-time NVIDIA card user. Currently I have ATI 9800 Pro's
in both my work and home machines.
The DX9 performance described by the Beyond3D article is consistent with
what we've been seeing.
Again this information is not official, so it is always possible that it is fake. But I think Inflatable will be happy that Asus is going to make Radeon based cards in future. We will have to wait until Valve releases the Half Life 2 benchmark to be sure about the performance of both ATI and NVIDIA 3D Cards...
