[SIZE="+1"]Background information[/SIZE]
People have previously mentioned that their Powercolor X800 GT's were being improperly identified as having R423 chips, even though they have checked and found that they are indeed R480 chips. People with such cards had asked if there was a way they could get it to show as an R480 chip. They had been given responses that there was no reason to make it show as an R480 chip. I have found that this is actually not true! I did some research on it and these are my findings.
I figured out how to get the Powercolor X800 GT bios locked to 8 pipelines so I could use it to get equivalent performance to that card on my X800 GTO2, so I did some benchmarks. I found that when using the GTO2 bios rather than the Powercolor X800 GT bios at the same clock speed and both at 8 pipelines yielded at least a 100 point increase (potentially a 200 point increase) in 3dmark05 scores at X800 GT clock speeds.
The performance increase seems to have to do with the driver for an R480 chip getting better performance than for an R423 (when you have an R480 chip). Maybe a result of optimizations for the R480? BTW, I also get higher overclocks with the GTO2's own bios than with the Powercolor X800 GT bios.

An approximate 100 point increase in their 3dmark05 score was reported.
In addition to that, PastryLikeDood has reported a 700 point increase with the bios change, which increased it up to the ~4150 score that is typical after the bios flash: http://forums.techpowerup.com/showthread.php?t=6056&page=9#post48158
Other people have tried it as well and also had an increase in performance, but I haven't taken the time to count them.
There are a few different bioses I've uploaded for this. None of these will identify the card as an X800 GT, since ATI's driver package does not support an X800 GT with an R480, which would be why the Powercolor cards don't have it set as such.
To determine whether your card is compatible with one of these bioses, look at your fuses data in ATITool. If CONFIG_DIE_FUSES looks like 0xFFFF?FFF and CONFIG_SUBSTRATE_FUSES looks like 0xFFFFFF9? where the "?" can be any digit, then your card is a candidate for being able to accept one of these bioses. If the fuses values are like that, then pick the bios that is the closest match for your card. If one for your card is not here, then post your bios so I can modify and add it.
#1 is the second revision of the Powercolor X800 GT bios, but modified to be identified as a Powercolor X800 GTO with an R480.
#2 is an actual HIS X800 GT bios from the iTurbo version, modded to R480
#3, #4, and #5 are a modified Sapphire X800 GTO/GTO2 bios with clocks modified to X800 GT clocks and subvendor id set to the company named in the file name.
#6 is the bios for the GECUBE X800 GT, modded to R480
#7 is the bios for the Powercolor X800 GT Evo, modded to R480
#8 is the first revision Powercolor X800 GT bios, modded to R480
#9 is the bios for the Club3D X800 GT, modded to R480
#10 is the bios for a GECUBE X800 GT 128 MB, modded to R480
#11 is for the Powercolor X800 GT 256 MB with Hynix 2.0 ns memory
All of the bioses are modded to 16 pipelines, so that all available pipelines will be used (all that aren't locked elsewhere).
[SIZE="+1"]Try the modded bios that is for your own card first![/SIZE]
It seems that the Sapphire X800 GTO2 bios may possibly make the card run at least a little hotter than the original bios on the Powercolor X800 GT. The ones starting with Sapphire in the name are the Sapphire X800 GTO2 bios set to X800 GT clock speeds. Try this later if you want to see if it gives you better overclocks/better scores or not.
Note: Most of these bioses are ONLY for the 256 MB versions! If anyone has a 128 MB version not listed here, please post the bios and I will mod it.
