HUH, what? 8O :?

Are you talking the nvidia 5900 pci/agp videocard?
If so it is dx9 capable.

There is a PCI Express version of it, this is what he means by PCX5900.

Yes it is DX9 compatible.

The NV35 FX5900XT chip which this uses is an unusual chip with 4 pixel shaders, 8 TMUs, and 8 ROPs. ATI tool will report 4 pixel pipes as it has 4 pixel shaders.

I cant decipher the rest of your post.

Yeah it was at 8x6 res. but with the settings set fairly high
and a.a. x2 and it was very playable.

It was in dx 8.0 mode though. still looked like my 6800gt in dx9.

Almost al games will default to DX8.1 path since the DX9 path is much slower for the FX series. It can play but it plays at half the speed of the equivalent of it's generation.

The Pixel pipelines you are seeing is actual pipelines of the FX5900 series, none were true '8 pipeline' designs, they were all 4 pipelines that could process up to two pixels per clock, however usually processed 1 or less depending on the operation, and when FP32 was called for (not PP FP16) then you only got 1 pixel per clock. Also the output was also dependant on what was needed as it could process colour+z and then just z as well.

There was alot of discussion of whether or not it was an 8 pipeline design or not early on, and later it was revealed what it was just 4 wider pipes. People still report both combinations (8 virtual pipes / 4 real piepelines).

ATiTool just reports what's there in hardware.

The FX5900 is fine for CSS, but it you plan on playing future DX9+ titles you might want to consider an upgrade in the future when you need it. For now it'll be fine, don't worry about the other stuff, unless you need shiny stuff.

I agree, but for CSS, he's likely more worried about raw fps even under DX8.1 than whether an R9600Pro might look prettier with reduced framerates.

I also thought if he's still on an FX5900 so long after the GF6600GT, X1600Pro and GF7600GT came out, he's likely not all that interested in the DX9 bling. But that may change when SM3.0 is the minimum spec for his next game.

BTW, if it's not UV reactive with an LED fan, you're just not trying hard enough. 8)

thats true, but too many games are coming out now requiring SM3 which is why i ditched my old faithful x850pro - old red i used to call him, cos he had a groovy Zalman fan with red LED :) , no UV though :twisted:
