Last upgrade: overclocking Radeon9800Pro:
I succeed to overclock GPU from initial 338 MHz memory a 378 MHz GPU core:

to 351 MHz memory, 392 MHz GPU core.

I also equip the card with new cooler - Thermalright V-1 Ultra, slightly modified to don't block nearby PCI slot.

even if overclockig is only by 2-3%, SDLbench faster by another 8%.

Nice! Just now, my Pegasos have overall score 3341.66 in http://hdrlab.org.nz/benchmark/gfxbench2d/OS/AmigaOS/Result/2155
It is faster than some SAM460Ex with HD cards, even if this card have no compositing under AmigaOS.
